     Buell1125 |
I have a 1125r. I think it surges more than it should. I have fmf pipe and eb ecm. Up to about 5000 rpms it surges like crazy. I replaced the plugs. I am very mechanical and can do about anything. First I just want it compared to other 1125's and maybe ideas of what to do. I do not get on here to much. If you think you can help let me know. I will compensate you some how. I am about to go on a 1300 mile trip it would be real nice if someone could help me very soon. e mail is karate4fun@charter.net | ||

First thing to try, unplug the O2 sensors and see if it goes away. I know it's not a real fix, but try it anyway. | ||

K thanks I'll give it a try. Stay posted so I'll know what to do or try next. Lol Thanks | ||

Just a fyi, it could be numerous things causing it. Faulty fuel pump or pressure regulator, faulty (dirty) fuel injectors, bad coil(s) or even a dirty air filter (not likely, but still possible) along with many other things on the bike. | ||

What are your fuel trim values? | ||

Thanks everybody for help and comments not sure if this is what you are referring to. I just run the diagnostics. No codes fuel kpa was about 500 at idle fuel voltage was 2.9 at idle, front & rear o2 was .4 front and rear fuel adapt was 100 after searching here that looks about right. I would have guessed low fuel pressure. now thinking injectors?? | ||

Tps reset? | ||

I think the TP resets itself at every start up on these bikes. | ||

First I'm going to say that there its a fueling issue, but the surge is a natural acurance. It's in all motors, there is systems built-in the drivetrain to take it out. Buells and HD's have rubber stoppers in the drive pulley to take it out as well as a few other things. If you have a lot of surge, I would look there first. | ||

I agree I'm thinking fuel. According diagnostic code fuel pressure looks good. so I am take my other bike, When I get back I' going to look at all fuel lines and replace with some injects. Thanks for all ya'lls help keep up on this I'll post after my trip | ||

Jdugger LOL!!!. > 5000RPM fixes everything. what was your 12,000mi service like? a couple laps at WOT I am totally kidding. I know you, know whats up. I also think the 1125 is much happier at higher RPM.... like every sport bike. I just think its funny | ||

Ok I am back I took my other bike on my trip. I am going to try to clean injectors once then replace. I know these bikes have a lot of surge but I think this is more than normal.That's why i wanted to have someone so we could compare. If this is normal I will not be able to handle it. |
