I've been reading a lot on the Crankcase Breather Mod, but had to dig around to find out how to do one.

I know there's another thread on this forum, that's what I used to get started on mine. I'm just updating the parts list, and adding pictures.

It's a pretty simple mod, so here's a step-by-step that should help you along.

Here's what you'll need:

(5ft) - 3/8" I.D. Transmission Oil Cooler hose, cut to the following sizes:
- 10" piece
- 2" piece
- 24" piece
- 18" piece
- 6" piece

(1) - Breather Filter with 3/8" connector
(2) - 3/8" Vaccuum T's
(4) - 3/8" hose clamps
(1) - Radiator Drain Cock with 3/8" threads
(4-6) - Zip Ties
(12") - Electrical Tape

Scroll down for directions.

Step 1:

Remove your seat and airbox cover

Disconnect the vent hose from next to the Fuel filler cap, then remove the airbox lid.

Disconnect the two vaccuum lines and the sensor wire from the bottom of the airbox base, then remove the airbox base.

Step 2:

Remove the two factory vaccuum hoses.
Remove the braided nylon sheath from the longer hose.

Connect the new 10" and 2" hoses with a vaccuum T.

Place the nylon sheath over the 10" hose.

The sheath is actually a little longer than the hose, but if you work it down it will fatten up and get shorter.

Wrap a few loops of electrical tape around the edges to hold them in place and keep it from fraying.

Step 3:

Run the 24" hose down the front of the motor, past the oil cooler bracket, then back along the frame support rail.

Connect the 24" hose to the 2"/10" vaccuum T, with the 2" hose towards the front and the 10" hose towards the rear.

Connect the 2"/10" breather hoses to the crankcase breather ports.

Step 4:

Connect the Radiator Drain Cock to the 18" hose.

Run the 18" hose up the back of the crankcase, then along the frame support rail.

Connect the 18" hose to the 24" hose using another 3/8" vaccuum T.

Conncet the Breather Filter to the third port on the vaccuum T.

Zip-tie the 18" and 24" hoses along the frame support rail near the filter. This should hold everything in place.

12-15-2008, 08:45 PM
Step 5:

Stuff one end of the 6" hose into the vent hole on the bottom of the airbox base.

Loop the other end over and stuff it into the second vent hole. The will seal off the airbox and make sure dirty air doesn't get past the filter.

Put everything back together, then go for a ride!

It will probably run like crap for a while until the computer can re-calibrate itself. It should smooth out after about 15-20 miles of mixed city/highway driving.

Good luck!

First off great write up.[up][up]

But just so you know the drain or petcok should go before the breather otherwise it will all blow out of the filter instead of going to the drain.[up][up];)

I am about to do this mod, and i'm curious as to what you mean fastxb12r? Instead of having the filter in-line, you should run a line down before it and then a line to the filter?

Buell_Cru
12-16-2008, 01:07 PM
See my edited illustration below for a better understanding. The drain should be in the front to catch all the head gases and oily residue. Then the filter should be ran off of the tee.

I was actually just getting ready to reply. It doesn't look like it in the picture, but the hose is actually angled down as it goes back.

Due to the viscousity properties of the oil, it will tend to stick to the inner walls of the tube. As long as it is angled this way, it will flow towards the drain.

http://www.atvcolorado.com/attachments/Buell/hoses.jpg

The filter will block any large drops of oil from blowing out the vent, so you don't have to worry about spitting oil all over the side of your bike. The drops will again drain down the tube towards the valve.

The internal volume of that last 18" piece of tube is just shy of 8 cubic inches, which is a little over 1/8th of a quart. Plenty to act as a catch can.

There are several different ways of routing the hoses, I just wanted something simple that didn't look too bulky. So far, I haven't had any problems with it.

It would be easy to mod this setup to match Buell_Cru's illustration. Just add a 3rd vaccuum T where the hose loops next to the air scoop. Run one line straight down, and the other towards the back.

Good luck!

Buell_Cru

I understand the details as far as adding grade to your line so that it will still drain in a downward motion but that wasn't explained for the guys with not as much mechanical knowledge.

Good mod.

Totally understood. In all honesty, if I had seen your post I would have done it that way. Less chance of clogging the filter from the inside.

In fact, I'll probably modify it this week to run the drain straight down. I'll post another pic when it's done.

Thanks for the heads-up.

great Write up. I agree that the filter should be up from the drain but you could leave it in the same location just rotate it up so the oil flows under the filter.

Urban_Assault
12-16-2008, 02:49 PM
I'm wondering now if there's a way to put a couple of schrader-valves on this setup.

One near the filter, to only allow fresh air in

The other near the drain, to only allow oil/dirty air out.

It would basically make a one-way downdraft airflow circuit. Would eliminate the need to drain the valve, still allow the system to breathe, and not allow debris back in.

Maybe I'll pick up a couple of schrader valves today and see if I can fit them inside the tube.

Any thoughts?

Used a single 3/8 nylon T and 3' of gas hose from Napa Auto. Used one of the "old" pieces of tubing to plug the cover holes-similar (a U) to what is shown in the pic. Nothing on the end..just terminated it at the muffler outlet. Havent seen anything drip from it yet and if it does, the exhaust pulse will simply blow it outwards away from any possible contact with the tire. Easy job-took maybe 1/2 hr and it does seem to idle smoother.

I don't want any oily residue getting anywhere near my back tire and I don't want any drip marks in the garage. My bike is my mark and it's with me wherever I go.

Dont know if you can see in this picture but i run a similar set up. Providing you drain the oil often enough there seems to be no problems. I usually check it every 250 miles.

Hi.
Great info and help. Just did the mod this evening. I'm not technically savy when it comes to this stuff, but i got it done.
Took it for a ride and feels better.
One question though, i was sitting at some lights for 5 mins and when i looked down at the filter it had smoke/steam/what ever coming out of it.
Is this normal if it just idles... i'm gessing the gasses that once went back to the engine.
Any confirmation would be great and again, thanks for the help.

Urban_Assault
01-31-2009, 06:51 PM
Mine does that too at idle, especially when it's cold out. (Just got the bike in October, so it's brand new)

It shows up more when it's cold, because the moisture that builds up in your crankcase is evaporating out. (Just like seeing the moisture in your own breath when it gets cold, or steam off a cup of coffee.)

Some of it is also oil that has reached thermal viscousity point, but again... it's pretty normal.

If it starts pouring tons of smoke out, then there's likely a problem. But if it's just a little, no worries... Mostly just steam and evaporated oil.

You can actually hold your hand over the smoke for a few seconds, and it will get wet from all of the steam. A little slimy from the small amount of oil, but mostly just wet.

If it becomes too much oil, it will have the typical "oil burning" smell that old smokey cars have.

Just curious about the length of the tubing and the change in elevation the oil has to travel.
What i mean is the tubing comes down first, bends and has a slight up hill climb before the big bend down.
I have opened the screw and nothing has come out and i have driven it over 100 miles, or isn't that enough.
Again, just curious.

I actually haven't had much in mine either. A few drips of water, but otherwise nothing. I've heard mixed results from everyone else. Some have to drain it every gas stop, others don't.

I'm guessing mine isn't as bad because it's a brand-new motor. If the rings are settled correctly and not worn out, there won't be much blow-by past the pistons and less burnt oil to vent out.

That's just my theory, anyone else have input?

Justin, how many miles are on your engine?

Also, on mine I don't have an "up". It goes straight back across where the filter is, then down. I avoided having an "up" because of the very reason you just pointed out.

The filter "T" is also angled slightly upward, to make sure no oil drips down through it.

Hey Urban.
Firstly i have a 2005 XB12S 13000 miles.
With the filter on the T joint i did the same thing and angled it slightly up incase of oil running in to it.
Here's a couple of pics how i routed it, basically like this mod. (Need to get some black ties)

Im confused as to why everyone replaced the initial breather hoses instead of just connecting them to the T connector and then running them back. Seems to save hose, and cut out a step to me.

Thaloc
02-26-2009, 02:40 AM
So yeah, that was totally easy. I completely blame you guys for confusing me up.

I left the initial breather hoses in place, just cut off about 2" off the one with the nylon wrap. Connected them to the T connector and ran a hose from there back between where the subframe connects to the frame. I placed my filter right by my left heel guard and the drain hose runs behind the the left peg mount totally hidden until I move it out to drain it. I got a blue filter so it matches my color scheme.

But ya, you guys and all ur numbers and measurments and **** confused the **** outta me. All anyone needs to know is get **** in 3/8". Period. Im going to write up a dummy version for us "Mechanically Challenged" folks.

Yeah, under the airbox, I used the stock hoses into a T and ran back except added one of the cool little air filters halfway down the "drain" line.

Did not read all the comments, but a small hint to do a pro job on sealing the holes left in the filter canister. Use a couple of covers used to seal holes in SS sinks, these fit perfect after you enlarge the original holes a little, it look smart too...you can find these in any hardware store,,, can post some photos later if any one is interested, but I am over seas at the moment.

I just finished my breather reroute. I tried to keep it hid and keep the bike looking stock. I hid the breather filter under the seat by the shock and ran the hose down the swing arm and by the brake line. This is just another option to add to the many ways to run the reroute. Let me know what you guys think of this positioning.

So when you say "re-calibrate" the ECM. Does that include pre-08 models??? I heard that when you do mods the Pre-08 models wont re-calibrate unless you have a program for the ecm??? Kinda lost, so any insight would be great. Looking to tackle a DIY project.

I did this mod last Thursday on my XB12STT.

I went out for a ~200km ride on Sunday with 80km of it dirt, and the low speed surging issue has all but gone. Makes riding dirt a helluva lot easier when you don't know whether you'll get around a slow speed corner without the chance of a surge induced high side.

Props for the mod creators!!!


P.S. Car parks are easy as now. I was thinking of putting on an XB9 primary sprocket to make low speed easier, but now I'll keep the std one.

good, good. I'm mid-mod since I'm doing a bunch of other stuff, so I have a question.

Dave I think it was you who said just having the hoses join together and run back off the bike, will cause downdraft vacuum on the system and draw out oil, no breather filter required. That's my plan but is that your setup? and if so how's it working for you?

Also what is the consensus on Tasha's setup with the filter higher than the valve covers (though it should be located out of the airbox)?

Sorry for the very later reply. I have a filter right up front, and the hose runs down a little past the side stand bolt(basically lubes the side stand spring lol). The way I figured it is the air enters the filter and travels out of the bottom hose creating lower air pressure above the filter drawing out dirty air and liquids. Being how the filter is in front, it gets dirty faster, but other than that, it's worked out well.

Stevenc150 thanks for the reply, i had the shop fix it and replace the rubber grommet and install a new fan but they said it would just happen again with the mod i did. I can't see anyway the mod would pull on the grommet anymore than how it was stock? Anybody with any ideals? This is my only transportation 20 miles from town. BTW after 200 miles its leaking oil all in the fan again, This sucks bigtime!

I did this mod on my new Ss and couldn't be happier about it. There's a 1/2 dozen threads on here about it and I think I read every one before I did it. so much thanks to all who contributed!

If it werent a brand new bike, I would have gone the cheap route and terminated the hose into a $5 paper filter, but since it was new, I spent the money and bought the best catch can kit I could find:
http://kdfab.com/Accessories.htm

Even if I didnt buy it, the printable instructions are useful:
http://kdfab.com/catch%20can%20instructions.htm

Only problem I had was with the hoses that came with the kit. They are pre-cut to the size for MOST models. They are a bit too short for the Ss, so I had to cut new hoses about 3/4" longer than the ones pre-cut for the other models (I used the extra hose they give you in case you want to route the filter to the tail). The kit comes with a metal breather filter that can be screwed into the back of the can, out of site.

The kit is over-priced, but if you've got the money, and you want the most professional looking installation, I would recommend this kit. For me it was worth $$ for the clean stock-look, and because there's no maintenance other than emptying the can once in a while.

My only complaint is that I gotta do this $%#&ing mod in the first place. As I see it, this aint a "mod". It's a fix.

thanks you for the pictorial instructions :D

I'm getting ready to do this mod but Had one, single question.

Is it better or worse or doesn't matter to use Urban Assualt's version with two hoses or, Thaloc's where he connects the original hoses with a T connector and runs a hose back.

Thaloc's seems quicker and simpler but I feel there may be a reason to keep the hoses separate.

Please Advise.

Thank you

is one of your hoses short or binding the gromet?
i used both stock elbows and reversed the front and rear where i added the t.
I see no advantage to running the hoses seprate to a bottle.

Another cheap alternative catch can is a small air line water separator. You can find them at lowes or home depot for less then $20.
I know its been posted before, lots of people have done it.
Just unscrew the glass piece take the filter part out and your good to go. The valve on the bottom isnt worth crap, so you need to either get a better one or plug it up. I just ran a 1/2 tap through it and used a set screw with some locktite red.
The inlet side comes from the crank case, and on the outlet put the small filter.
Its nice because you can see how much is in there. You then just unscrew the cup and dump it out.
Its amazing how much gunk comes out after a nice spirited ride.

Sorry I dont have a better pic, but you can see it right under my air scoop behind the oil cooler.

I chose a little different routing, what do you guys think?

The hose snakes behind the rear cylinder, I zip tied it to the line that runs down to the oil pump to keep it away from the engine. Just crammed a bolt into the end to act as a plug. Sorry for the shatty pictures, it was late and I was FAR too lazy to get out my camera.

In my opinion, that is by far the best way to do it.
I looked into the same solution but couldn't come up with a good place to mount the separator. (although I never actually bought one and tried)
Can you give some detail on how you mounted it?
Thanks

Stevenc150
08-26-2009, 04:30 PM
I didn't use a catchcan, just left the end of the hose open. I do have an air breather filter on it though, the purpose being to allow drainage while the crankcase "breathes".

First of all thanks to Urban Assault for posting the instructions and the pictures. Great write up.
Second, if you have not done this mod already, get off your butt and go do it...NOW!!!
I just did a 180 mile ride with some friends. I did this mod last night. I immediately noticed the difference. It was especially pleasant during a 12 mile stretch of S turn switchbacks and low RPM's. The bike was so much smoother.
This is by far one of the easiest, cheapest and most productive mods for the bike. I added some pics, since I did my setup a bit different. Seems to be working great. I will post if anything changes.

I did this mod. and have changed the spark plugs and spark plug wires but i am still having an issue with sputtering when I first start the bike. Oh, I have also tried going to different gas station and use at least 91 octane for the fuel and have changed the air filter.

Does anyone have any suggestion as how to correct this issue?

I appreciate the explanation since I'm just learning. Thanks again.

I just took delivery of my new buell this weekend and i notice it sputters and stalls at low rpms. I was hoping it was the low mileage and the ecm wasnt adapted yet...Now i think ill just do this mod right out of the box. thanks for the insight [up]

driftingswiftly
11-01-2009, 06:48 PM
There is some pretty great info here, but i still have a question. Why Is everyone using so much hose and running everything all over the place? Can't the hose the runs down simply T off to a filter and have a few inches for collection. This way the whole mod would terminate right around where the air scoop is. Is there any need for all the excess?

Kplus12
11-01-2009, 07:19 PM
Ive noticed that i get a good amount of moisture buildup over a short period of time. If i had a shorter length of hose after the filter I would have to drain it everyday (roughly).[smirk]

driftingswiftly
11-01-2009, 07:42 PM
yeah, i guess i understand that, but I am kinda referring to how a lot of the tubes are run all the way to the back. why not just shorten it all up and make the collection however long you want? I'm not bashing, i am just about to do this and I would like to do it up short but don't want to be missing any reason for having it so long.

bardo688
11-02-2009, 12:27 AM
uh noob ? (havent read the whole artical in a hurry)
What exactly does the breather mod do? get rid of the hiccup rocking in first gear?

driftingswiftly
11-02-2009, 02:18 AM
yeah. I just did it and only used about 30" of hose. i just ran the tube down the inside of the air scoop. T'ed off the filter and continued the like about 6" form there. all near the front. Whats the deal with the filters tho? I feel like they will clog up fast...and will the wet be an issue?

bardo: Yeah, that wsa my main objective. low rpms are smoother so traffic, constant rev turns and wheelies are more predictable. I definitely notice a difference. Its nothing life changing, but it is for the better no doubt.

Stevenc150
11-02-2009, 04:18 AM
Drifting, did you close the end with a plug or soemthing. If so, you'll be draining fairly often.

I left mine open to drain on it's own while riding, so I ran mine all the way down and up and under the driver footpeg. Anyway, most run it down towards the bottom end for draining convenience I guess.

driftingswiftly
11-02-2009, 01:46 PM
Mine is open right now but just bc they were out of pet-cocks. I am planning on plugging it, and have 6' for collecting...will it really fill up that fast? I am hoping to only have to drain it like every 250 miles or so.

marko138
11-02-2009, 02:49 PM

11-02-2009, 03:39 PM
Thanks for the DYI instructions... followed the instructions for the re-routing and then used a catchcan + breather setup...

No difference felt during riding, but 20miles were enough to collect 2-3ml of clear liquid...

11-02-2009, 09:05 PM
So i did the mod the other day, I do notice a bit of a difference...but I have experienced a drawback too. it might be just me, but you know how everyonce in a while when you rev it from straight idle (like at a light or maube after you first start it) and you happen to catch it at the wrong point in the cycle and it spits and boggs down bit. Well it has never stalled before when that happened, but it stalled once since the mod. I don't think its a huge deal, but any ideas? I would feel like such a tool if I reved while makin eyes at a girl at a light and my baby sputtered out under me. haha

Stevenc150
11-22-2009, 09:32 AM
I'm assuming you're talking about a catchcan when you say reservoir - it depends on the reservoir and you're mounting location. Below is the vid:

First, thanks for the vid link. I'd seen that one, but I'd also seen a clip of someone unscrewing and dumping the liquid out of the reservoir on the compressor filter used as a catchcan, like in wavex's picture. I'm trying to figure out how to secure/mount one like that.

Stevenc150

No need to, it'll just clog up eventually. As long as you keep it drained so it doesn't overflow into the red filter, you should be golden.

Baal
12-02-2009, 05:07 PM
I don't know much, but I would be reluctant to face the filter into the wind. I don't think you want positive pressure on the downstream side of the breather system. Hopefully more tech-savvy folks will comment.

I don't know much, but I would be reluctant to face the filter into the wind. I don't think you want positive pressure on the downstream side of the breather system. Hopefully more tech-savvy folks will comment.

I placed my filter in the front with a hose running down near the kickstand bolt. I figured air passing over the filter and air flowing around the hose at the bottom would cause negative air pressure causing air to be pulled out of the crank case. I have had zero problems and I rarely have to clean my filter.

Johny Kidd
12-22-2009, 03:59 PM
Johny...that looks great. -Thanks ! [cool]


Johny Kidd: What are the dimensions of the tank? -It's welded from square profile pipe which outer diameters are 20mm x 80mm (millimeter). There is no baffling inside the can, just empty pipe.

I did modify it a little since the pic was taken and now its waiting for new paint. I will post a pic when ready and installed!

Then for the fuel tank I zip tied it to the air box

Why did you plug the fuel vent tube???

According to the owners manual
http://www.buell.com/om/99474-09Y_en/file-8.asp
a "Obstructed fuel tank vent valve or pinched vent tube." can cause "Starts But Runs Irregularly or Misses"

^ yup, the tank needs to breathe. As the motor consumes fuel the empty space needs to be taken up by air. Otherwise you create a vacuum in the tank and overwork your fuel pump. I bet when you remove the gas cap you hear a sucking sound now.

Yeah baja, there is a loop behind the left rearset that is meant to hold that hose. It should be routed down there in case of an overflow.

hey guys am I supposed to have a hose running over my rear shock and ending right above my rear fender? I was wondering if maybe the person who had my bike before did this mod or if that is factory

Have to add my conclusion,

Singlehandedly the best thing I've done to my bike besides putting the pipe on it. Such a big difference in torque from takeoff without having a worry in the world about it stalling. I actually dumped the clutch today with only a cunt hair of throttle and it wheelied from a stop. No hesitation what so ever.

Now keeping the front end down is becoming a big worry :D

browland,
I think that the hose you are referring to comes directly from the crank case (under the rear header in the starter area). on my 08 this hose runs straight up to the top of the rear shock and it is wire tied in a loop there, about 2" pointing back down. this is to allow gasses and vapors to exit the bottom end as the oil heats up & expands & allows fresh air to enter as the oil cools. I'm guessing that whoever had the bike before you might have just relocated the hose as shown in the pics, or maybe that's how it was run from factory on yours?
Anyway, it does not look like the breather mod has been done, you should look under your air box to confirm.

if the mod is done it will look something like this:


http://www.buellxb.com/buell_images/5461_20100103104824_L.jpg


If not, the 2 hoses I marked will be run up through the bottom of your air box base right next to the IAT sensor.

If you do the mod, I think it looks better with the breather somewhat hidden under the back of the bike instead of out in the open above the primary. just personal preference though, it's your bike, make it suit you [up]

yep thats the one I guess the rough edges on the end of the hose just made it look like a at home mod and since every pic I look at around the shock area doesnt have a hose like this I was wondering. Thanks for the help guys![up]

Guys, I need a little help. I did this mod on my cit-X months ago, I've already put more than 4 thousand kilometers on it and I did not get anything from the 'drain' is something wrong? Here are the pics.

http://i198.photobucket.com/albums/aa181/vblasques/25Apr_0004.jpg

as you can see the hose continues its way down.
Why don't I get any water or dirty or anything from this hose? Is the filter doing a great job or something is wrong?
Thank you people!

bolt08
01-05-2010, 02:36 AM
Stupid questions:
1. you do have a plug or canister on the bottom of the drain hose?
2. Does the drain hose have continuous fall all the way? no low spots where anything could be laying?
3. while riding, do you notice any steam or anything exhausting from the breather?

the only thing I got out of mine was about a tablespoon of water after bout 400 miles of riding and I drained it shortly after riding. Maybe there is a chance that it is evaporating out if you ride then park it and let it sit [confused]
keep us posted

vitor_br
01-05-2010, 01:50 PM
Hey bolt.
Yes for the 1 and 2 question and as for the 3rd I never really noticed I'll pay attention now that you said that.
Well, I believe everything is in order.
As for the changes I didn't feel any change on riding, it still chokes sometimes, but one thing is for sure the oil level isn't going down as before. I rode approx. 5 thousand km and it's still good to go.
Thx guys!

I put 300 miles on my bike and barely had a drop of water on the tip of the bolt I have clamped in the hose. Does beating the crap out of the bike and high revs keep it from collecting water/oil vapor?

Yer guys, give me a few days to work out what i need to do and the cost involved, ill have to track down more filters, drain cocks and some more stainless etc

Full kit would be bad ass but I'd set it up both ways.

A kit would be good for your potential customers, but sourcing the hose and barbed fittings might be a pain, plus increase your shipping costs too. I think if you had to change the mounting screws for the tank you might want to include those. I'm game for whatever you come up with. What's the scoop on the filter?

You guys that don't have any oily water stuff in your vent... Just wondering where you are from... Arizona?... could it be from less moisture in the air (less water coming into the engine)? Maybe i'm way off but just a thought....

Central California 20 miles from the coast. Tons of moisture in the air, but it is garage kept.

For the guys with lots of fluid, are your bikes kept outside?

jet6
01-15-2010, 05:03 AM
Ok guys, done some quick sorting, the filters are no issue, can get them no worries

I agree, adding the hose etc would add to shipping cost and its not hard for you to go buy 1m of 3/8" hose, some hose clamps and a barb tee

I can supply all the parts and its no pain to me, all my suppliers are close and handy anyway


Ok so after doing some thinking i also think it would be a good idea to offer them in raw stainless, because i think the paint might get damaged in transit, ie stuck to the wrapping or something like that


What do you guys think, im still looking at the prices, but there not as cheap as i thought when you have to buy everything, roughly would be about $150US for the complete kit, bolt on, but i have to finalise this yet, plus postage

I have a question for the brilliant minds at BuellXB.com, but you guys will suffice...
I kid I kid :D

(it's more like a ramble now that I think of it...)

but seriously, you guys know your stuff and I am always impressed and you continually edjamicate me aboot BamBam and Buells in general.

on page 5 of this thread I did my breather re-route...
a few weeks later I did the airbox delete...
since the re-route was done I have a abnormal amount of liquid in my catchcan even after short blasts AND it seems to be more gas then anything else.

BamBam came to me with K&N filter and D&D exhaust and race ECM...

my brain is saying 'hey, it seems like he might need to be re-mapped'

He runs fine, nice and crisp throttle responce, great power across the powerband, he can lift his front tire running thru 1st-3rd without trying too....

I fiddled with his idle cause he seemed to be running a tad under 1000rpm when I first got him (last Oct)and when we rode today he idled fine but over the last few weeks when we have had a good day to get out and ride, he seemed to idle a little high...[confused]

I really don't have much experience with hooking comps to vehicles and have read up aboot emspy and the like but would be wadeing into unknown territory....so any feedback, ideas or just the magic answer to everything I need to know would be appreciated. ;)

Matt

Baal
01-22-2010, 05:54 PM
Is the filter housing hollow, paper filled, mesh, or what? I think it looks a lot better than the exposed pleated paper ones, and the tube you mount it too eliminates the need to "lash" it to something to keep it from flopping around (or at least so it seems). Really sano.

As far as finish, I can either prime and paint it or take it to be powder coated, so however you want to do it is OK. The only thing I haven't been able to find is barbed brass fittings.

I'd asked about where you were because you had said $US; I figured you had to be somewhere else other than the States.

Well, I'm certainly still interested. Keep us posted, and depending on how much we're talking about, all in, I'm game.

jet6
01-22-2010, 06:56 PM
You wont need any brass barb fitting for my can, it has 3/8" stainless Swagelok tubing welded into it, you only need some 3/8 hose, some hose clamps and a 3/8 tee fitting

As for the filter, its alloy and the cover is threaded on, it has a foam insert thats removabale and cleanable inside, with my set up you can remove the filter top and clean the filter pad without taking it off your bike

If any one is interested feel free to PM me or contact me via email at matt@thumpainc.com

I do believe its for the XB's...

here is a cut/paste from one of the most knowledgeable people on this forum....LeFox

"to explain the concept.
original routing re-uses already burned gasses, which still have some unburned particles into the mixture and route them back to the inlet to burn again, thus actually burning the mixture twice.
this causes less unburned particles to be released into the air, which is better for the environment.
in this mixture, there are of course also exhaust fumes which don't burn that good and which prevents your engine from running optimal, especially at low rpm when there's not enough fresh air getting mixed with the already burnt mixture.

so, by re-routing this, you are no longer pushing fumes back into the engine, but filling it with a fresh air/fuel mixture, making your engine run smoother and healthier.
but, although minimal, this does affect the environment.
and, since you are no longer re-burning that air/fume/unburned particle mixture, you will be adding more fresh air/fuel mixture. Which will give you some minor changes in your gas/mileage. "

If you click on his Profile as well as mod Stevenc150, you'll find a plethora of knowledge

without a filter ( or open hose to the outside) to let the gases ESCAPE from the crankcase or vented back into the air intake to be burned in the combustion chamber,, it would build up excessive pressure in the crankcase and also cause poor idle , it is a basicly a pcv valve just like on your car it needs to be either vented to the outside atmosphere or vented back into air intake (pcv valve uses vacuum from the intake manifold to draw the fumes from the crankcase)... it needs to be vented out or directed back into air intake.

I used an old wrench for the bracket. Here it is before being bent to fit.

Here it is installed to fit

http://www.buellxb.com/buell_images/5550_20100302183715_L.jpg

The bottom of the original catch can had a pressure release that wasn't sealed 100%. I broke that off and JB Welded a penny at the bottom of the catch can.

http://www.buellxb.com/buell_images/5550_20100302183905_L.jpg

As you can tell some ingenuity was used to make this happen. Take your time and put some thought into your mods to make them original!

If you have any blow by or water vapers ... , you'll have a mess at the end of your tube. The catch can "catches" this mixture. When the pressure drops in the crank case, it could suck dirt into the tube if there is no filter.

my bet is that it's a shift knob for a car [confused]

That's my guess as well. Interesting idea if it is!

Thank you for you advise ...... quick question do I need to have that little filter installed or not?
Or I just connect two pipes together with t connector and drop pipe by oil cooler? Some one told me that I do not need a filter, just pipes together as is no back pleasure on the pipe from 2008 bikes.
Is you bike is lumpy? What petrol you use on your bike? I have tried in UK Shell Vpower and it made difference a bit!!! I have changed on mine to Iridium plugs help a little do you think breather mode will help further. What about exhaust on yours, I have been replaced under warranty my one and second now rusting away after just 3 weeks. Any suggestion on exhaust….Remus do I need powerizer, replace headers, or any other exhaust recomendations?
Sorry for the thousand questions!! My bike is XB12X 2008 model in UK
Thank you

The filter is not manditory but it is recomended because these crank breather sucks and blows stuff in and out so you do not want to suck any bad stuff in to your engine. Those little filters are not very expensive at all any way.

Thanks for the writeup!!! I'm doing this saturday. Gonna use either a bud light can or the water seperator as the catch can. Awesome job!!

Buell_Magic- any word on your catch can? What's it made from?

My bike still has yet to have anything more than a tiny bit of buildup of oil and water mix on the tip of my bolt I have clamped into the end of my drain hose as a stopper. The filter got a little dirty but after I washed the bike its completely clean again.

For you guys getting a noticeable amount of water and oil, are you in cold climates and never rev your engines out when you go on any rides? [confused]

did mine last summer. I didn't want any hoses to show.
I also have a NOS and Rockstar bottle :p

if you look for them yo can see the routing, I did extra hose instead of a filter and ran it down with the exhaust pipe so any extra fluid can either vaporize or drop onto the street out of sight.

Has anyone done the re route on the 1125r or cr?

Pockets, sorry we have been up in Canada and havn't had much time online. Indeed it is a shifter. I drilled a hole in the top piece that allows the fluid to drain and be held in the twist off bottom piece.

Looks good twisted. I just did it yesterday and went on a ride. So when I back I went to drain it to see if anything would come out...then I realized that I never actually closed it...doah

I just did this at the weekend, just like the set up Twistedrose has done.

WOW what a change. I should have done this a long time ago. It was easy, cheap and has improved the way the bike runs by at least 50%.

I do think it is also a bit more responsive now.

I'm doing the breather reroute , and thought i would show you the reason why you should consider doing the mod , Look at all the oil and gunk and dirty crap that is all over the top of the air box and the bottom around the air sensor and the hoses from the PCV valves and look at the oil build up on the filer (blue seal and the filter media itself) all that was getting sucked into my engine. after the breather mod is done it's going to be all clean air..

also even if dont do the mod take a look at your pcv valves, my rear one was leaking oil mist and gunk all over my rear rocker box cover , the leak was from where the hose ataches to rear PCV valve with the plastic zip tie , it was very lose causing the oil mist to get blown out all over the rocker box cover . what a mess . it took an hour to clean it all off , very tight spaces in there. so take a look at yours by taking off the top part of the air box cover then look at rear rocker box cover to see if it has dirt and oil on it, the front can be seen by looking under front of frame(fuel tank). just thought i would give you guys a heads up to check for this on your buell .

haha, I guess my bike does use the whole rear suspension travel :) I turned the breather filter outwards, I am a very large rider, and started to squish the breather filter ! No further issues.

I finished this mod a few days ago and am really enjoying how much it has changed the low rpm range of the bike. One issue though, I ran my line just like twistedrose and mounted the filter in a similar location. I am experiencing a tremendous amount of blowout from the filter. Like it is covering the swingarm and pratically dripping out of the filter. I have the end of the line plugged with the radiator plug. Should I leave it unplugged?
