ok so i began having problems with my bike jumping out of second gear last week. I took it to the shop where they were going to replace the clutch to see if that would correct. it didn't. I have since determined that its the shift fork and/or gear dogs. that sucks. anyway, while it was in there, i had them check the valves and timing chain. he said they were both good and under specs. but now my bike runs like crap. it sounds different than it ever has and it has no power up to 5k rpms. i've got 16k miles on it and have had conintuous performance out of ever since i originally bought it. the mech says it's nothing that he did. says i need to get a power commander to correct the problem. why would i need to do that? i've never needed one up till now. anybody got any advice to offer? i think he's getting thrown off by an error code from the exhaust servo. i've got a muzzys on there. there was a servo limiter to keep the FI light from coming on, but the servo gave out about 6 months ago and the light came on. no decrease in performance though. thanks in advance for any help.
