    AFV stays 100%

    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 kind of thing on motorcycles but it is very interesting. And it makes me like my xb even more.

    Completely clear. Thanks for the explanation! Again

    AFV stays 100%

    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, for example per 1 instead of per 5. That's why I asked here.

    AFV stays 100%

    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 good starting point. Thanks to being busy with all kinds of other things, I only got around to taking...

    AFV stays 100%

    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 will use that one.

    AFV stays 100%

    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 now the next thing I wanted to do is to know what my AFV is. I have never looked at it before...

    Repairing chin fairing xb12s

    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 it. I have searched the internets but cannot find exactly which material the fairings are made of...

    xb12s - refitting stock muffler - what about the exhaust valve?

    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 allready wanted to do. Also to let the bike run properly with the new stock exhaust. Thanks for the...

    xb12s - refitting stock muffler - what about the exhaust valve?

    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.

    xb12s - refitting stock muffler - what about the exhaust valve?

    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.

    xb12s - refitting stock muffler - what about the exhaust valve?

    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 in place and plugged in but the cable is zip-tied away near the engine. And has been for a long...

    Flashing lights flashing quickly when engine is not running

    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 cause and if this is maybe a sign of another problem. Grounding issues?

    Buell XB vital checklist

    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 thought by myself two things: - I, with my 2004 xb12s with 50,000+ km's ridden (~31,000 miles)...

    xb12s sometimes doesn't start

    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.

    xb12s sometimes doesn't start

    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 bike today, I hope it still does after the many testing actions of yesterday.

    xb12s sometimes doesn't start

    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 corrosion, all were protected with some white grease (Vaseline we call in the Netherlands. I don't know...

    xb12s sometimes doesn't start

    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 local motor store in my town (mainly Japanese bikes) or is it better to go to a Harley dealer or...

    xb12s sometimes doesn't start

    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 piston velocity, compression is not present in a engine that is not running. So before the bike has a...
