| 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. | |

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

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:
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

| That IS the crankcase vent that comes out from the starter/rear cylinder area. | |

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!

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.
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! |

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
keep us posted |

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! |

vitor_br,
you may want to look into the NGK iridium plugs (DCPR9EIX) they helped my bike out a lot with the cough/choke, a lot smoother now

| 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? | |

| 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.... | |

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
Would you want them as a whole kit with hose all cut to length, T piece etc, or just the can and filter? Matt |
