Out of curiosity, what would cause the TPS to go "out of whack??" I haven't ridden my 1125R in almost a month (I was on a cross country trip on my Beemer) but when I went to take the 1125R out for a spin it was responding VERY poorly. I'd roll the throttle and nothing would happen. I'd roll it more... still nothing. Roll it a little more and then suddenly the bike would just LAUNCH. Scared the living crap out of me. Ran through the TPS reset procedure and all is well but I'm wondering what happened in the first place? | ||

Someone posted something similar a few months ago. I can't remember the resolution but do a search and find that post. Sorry I can't help. | ||

Jaime - Have you tied the butterflies and de-noided? Sounds like your throttle butterfly/flies are sticking, winding up the spring linkage and releasing. At any rate it sounds dangerous. Check TPS in Diag Mode and see what it does static, then start it and see if it's the same. I'd pull the airbox and filter and have a quick look regardless. Let us know if you find anything.

I've done nothing to the noid. It's still there, but the Erik Buell Racing ECU no longer activates it. I've had the ECU in place for several months now, working properly. It was just weird... I was away for 3 1/2 weeks on my Beemer. When I got back, I put the Beemer away and took the 1125R to work and I felt like I was riding a bucking bronco until I figured out what was going on and reset the TPS. I'm PRETTY sure it was running fine before I left. No one else would ride the bike while I was away, either. Really strange. | ||

This happens to me from time to time if the bike sits for awhile. First do what zack said. The noid creates unneeded resistance and tieing the throttle bodies together makes them open and close together. After you check and do all that lube the throttle bodies and cables then reassemble, being carefull with the breather is a must. Mine needs constant use or lube I believe it deals with the moisture that builds up from washing or something else. Just a guess. The only thing I know for a fact is that when mine acts this way a little lube and throttle movement and she is back to eating rear tires. Good luck report back please. | ||

not sure on this, but could a low battery situation cause the computer to 'forget' where zero value is? seems to be a theme after bikes sit for extended periods... | ||

Sticking butterflies. Q-tip and some WD-40 on a couple of swabs should do the trick. | ||

So I'm guessing it wasn't REALLY the TPS reset that fixed it... just the simple action of quickly opening the throttle and snapping it closed freed up the butterflies? Interesting. Thanks. |
