Well, I dont know how else to put it my buell runs like sh$%!
I've done the mods, even paid Mike to tune the ECM, of corse he decided to retire right in the middle of the tuning process. [mad].... At least I hope this isn't how its supposed to run.

So here are the details, she starts and idles fine, but runs terrible if the outside air temp has changed more than 8 degrees (until you have been rideing for a while) then it gets better, sort of, at any temp cruising between 2000 rpm and 2600 rpm at a neutral throttle position it has a miss, not huge or constant , but VERY annoying. And then we have acceleration, during an agressive roll-on (quarter to half throttle and progresing)it pulls great. but at WOT it falls flat on its face until about 3700rpm then it hits before that it makes a ton of noise and what seems like no power.

If anyone has any ideas or can tune and would like to pick up where mike left off at this point I'd give my left testicle to have this bike run, it just looks too good to run sooo bad.:(
 
I had that 2000 rpm range miss.. ended up being the wires from my ecm rubbed on my negative terminal lead and was shorting intermitently. It seems the vibes at that rpm range was enough to cause the short. It would be a quick but sorta violent cut off for a split second. It got to the point where my bike would not start.. ecmspy told me there was a short to ground.. might not be your problem but check it out none the less.
 
Don't get me wrong I respect the hell out of mike, and he deserves his space the timing was just bad. I dont want to push him, for what he charged I dont feel like I got boned or anything.


Trill, Thanks I will have to look into that, but my problem isn't really a complete cut-out its more just like the motor isn't happy at a fixed rpm[confused]
 
i know what you're talking about. Mine does that too when it's cold. It's around 2500 rpm, 25% throttle, it coughs. Once it warms up, it goes away. I think that has something to do with the cold start enrichment
 
This is the spot!
