Thanks for all the support here from this forum. So much information to find. I've learned a lot lately about ECM and logging with buelltooth and editing settings from ecmspy and and. Never done this...

Completely clear. Thanks for the explanation! Again

Not exactly, that 12750 value was for '02 Setup - Closed Loop - Limits - Minimum RPM'. For me it is now back to 600, as it should be originally.
I expected the AFV to be adjusted in smaller steps,...

Ok! Great.

OK. Bump my own thread. After allmost a year.
I reset all the ECM settings to the original settings and I loaded a fuel map from rev-mo.com, the "Race Tune for Stock Exhaust". This seemed like a...

Ok thanks, clear. I have not used the standard program because I do not know the exact source. I do now have a requested EEPROM from rev-mo.com and I read that it is a reliable source, so I think I...

Hi,

I am in the process of building my xb12s back to the stock exhaust. I have got the exhaust valve actuator moving again. It turns out it was still functional but only disabled in the ECM.
So...

Hi,

One of the many previous owners of my xb12s has somehow glued or melted the three chin fairing pieces together. Not a bad idea I think, but one of the seams has cracked, so I want to repair...

Yes, indeed.
I have a Buelltooth stick but have minor experience in using it. However, I hooked it up and saw that the valve is disabled.
This is a good moment to dive into the ECMspy, something I...

So if I understand correctly, once I turn on the ignition key I should see the actuator move? Because I have tried, but it doesn't move.

Ok, thanks!

Almost all info that can be found about the exhaust valve is about how to get rid of it, not about the advantages.

Hi,

I have a 2004 xb12s with an aftermarket exhaust. I don't like the loud noise of it and have bought an original stock exhaust to replace it.
The exhaust valve actuator on top of the airbox is...

Thanks for the answers, I will look into the NO money LED flasher mod!

Hi,

I've got a 2004 xb12s. When the engine isn't running the flashing lights are flashing quickly. When the engine runs, they act normal.

Not really a problem, but I am just curious what is the...

Hi,

Now that I'm busy with my Buell I read a lot of technical Buell stuff on the internet and I came across this article: https://www.twinmotorcycles.nl/artikelen.asp?cid=7&aid=620 . Great info! I...

Normally it starts almost instantly and now it took some more crankshaft rotations before it ran. Maybe 5 or so.
Not disappointing after all that fuel pump priming of yesterday.

Ok, thanks, I'm going to take a look at the handlebar control also.

And I was not aware that there was fuel injected every time the fuel pump primes. So thanks for that warning. I'll start the...

Ok. I'll leave the battery discussion for what it is.
I had a day off work today and spent some hours looking at the Buell.
All the connections and ground points seem to be in great shape. No...

Thanks, great advise, I like to be able to do it myself.
I am not sure my volt meter is fast enough to spot the voltage drop. But I can give it a try.
When I get my battery tested, should I go to a...

Ok. I think you're wrong. But maybe I am wrong. Please tell me.

Before the bike has a compression bump, the pistons have to build up compression. Because compression have to be created out of...

Wow thanks for all the replies!


No, I am sure it was not a compression bump. Even with a compression bump you should hear some clicking noise from the engine. In this case I hear nothing at all...

Wow, a lot of info in those topics! Nice.
Also the 2008 Buell XB Models Electrical Diagnostics Manual 99493-08Y looks like it will be very usefull.

One question lunaticfringe. Why is the number...

I don't know how old the battery is. I think it is just the regular one. It is fully charged and when the bike does start like normal (which it does most of the time) the engine cranks over with a...

Hi,

I have an 2004 xb12s which is an awesome bike.

But, approximately one out of every four times I try to start the bike, it doesn't respond to the starter...

Ah, humor. I have it too.
