So I have a 2000 cbr 929.. bought it.. same day I got it.. it dropped a valve.. replaced head.. headgasket and etc.. even changed the harness.. added a power commander 5.. now.. the problem.. it idles way to low and dies and when I hit the gas it bogs down.. in every gear.. any help would be greatly appreciated.. my mechanic said maybe a tps.. is there anyway to clean that? Do we have to sync the throttle bodies? He's even stumped on this one.. I'm pretty sure he didn't sync the throttle bodies but is it necessary? Plz help!!!!!!!! I've had this bike a year and only rode it twice
Absolutely should sync the throttle bodies, anytime anything is changed in the valve train, including valve adjustments. That may not fix your problem, but it could cause others once you get this one sorted.
Well it's weird.. it seemed to idle better with the old wiring harness on it.. had it switched out cause it was dropping voltage.. now with this harness (no cuts in the wiring).. it seems to run worse than before
It's throwing a code about the servo.. he done away with the servo and tacked the exhaust I believe is what he said.. we put a servo buddy on the bike;but it still flashes the code.. could this be the problem?
I'd say check your charging system make sure you have good voltage when the bike is running. You said you changed the harness double check all your ground connections. Make sure nothing was left unplugged. Also make sure that none of the coil and injector plugs were accidentally swapped.
