08 Uly Drummer S/S EBR ecm. Misses seemingly on one cylinder only when hot. Most often noticed accelerating 4-5000 rpm but lately started doing it at the end of last ride at 3500rpm. Will spit and sputter at times then take off again and run fine for a bit.??? | ||

Hopefully you'll get it figured out. Why Buell owners mess around with Drummers and the like is a mystery to me. Why change mufflers when it necessitates getting a different ecm and then all the problems that seems to cause. To each his own, but a noisy muffler usually just translates into hearing loss and a crappy running bike. | ||

Sounds like a classic case of the cracked ECM. Check the seat pan for rub marks. If the seat pan touches the ECM, more than likely, it's cracked and needs to be replaced. When you get the new one, either relocate it or build some kind of armour to protect it. | ||

I don't believe it's related to the Drummer or the ECM, though those were put on recently. Seems electrical- heat and sporadic. Tried plugs as was time for that anyhow. Going to go over the wiring and connections to ecm. | ||

Does it with the stock ecm and the EBR ecm. | ||

Also did reset TPS. | ||

Check your grounds. Might have plug wire leakage. Maybe intake seal leak. | ||

Check your plugs. Mine behaved near identically. Finally found that one was fouled. -Brinton | ||

+10 on Electraglider post. Check your grounds. On two occasions I had the same symptoms. First time I tightened the ground and three weeks later it happened again. Then I actually did it the right way (I think). Take off grounds, roughen the frame under the ground, apply dielectric grease and retighten. 5K miles later no problems. BTW is this actually the right way or just luck? | ||

Could be a lot of things... it will take some hunting. On my Uly (post accident, which was no doubt a factor) there were a collection of issues to track down. All failed at different times, but were close enough together time wise that they could have easily overlapped. 1) ECM connector location (fixed before I got the bike with factory post and reolocation kit, fixed even more by me putting a thick pad of high density foam over the top of the ECM so I squish the body of it instead of the connectors when my seat squishes). 2) Wire bundle going down under the steering neck (wire cracked internally, probably caused by me stuffing a horn under the airbox and restricting the bundle freedom of movement, or maybe caused by the accident). 3) Chafe point on the wire bundle going up beside the front final drive sprocket (not all the way through when I found it). 4) Bad crank position sensor. 5) Chafe point where throttle cables hit wire harness (caused by me routing things wrong on post accident engine rotation work). 6) Bad ground when I forgot to hook back up the big braided ground strap between frame and engine (it tucked back up on rotation and wasn't obviously dangling, so I forgot to hook up the other end of it). So anyway, it just took some thinking and a bit of digging. And some patience. | ||

Okay, my previous post was incorrect, swapped ecu back to stock and runs good again, e-mailed EBR to see if I missed something, but no response yet. Was mostly hoping it was something else I guess. Oh and I did check everything else out that I could. Still hoping EBR has an idea for me, as I do like all the other things the race ecu does ie: fan, exhaust actuator removal, evening fuel front to back cyl. | ||

I have has an experience almost exactly the same as yours recently... http://www.badweatherbikers.com/buell/messages/142 838/690211.html?1345907567 Runs great with the stock ECM back in... |
