Did you tighten the boots from the airbox to the throttle bodies properly? Is the AIS tube to the airbox secure? Are the vent tubes to the gas tank mixed up? Is the connector to the fuel pump tight?
I have never synced the throttle bodies. I'll have to learn how to do that. Thanks for the help. I really appreciate it.Rough idling is a symptom of out of sync throttle bodies. How many KM since this was done last?
I thought it could have been that. I have a power commander and have tried a few different tunes (it's a homemade exhaust system so I don't have an exact match) and no matter what tune I try the problem stays the same.Get the AFR checked, your new exhaust could have changed it. Possibly leaned out at light load.

Good thinking. I've tried everything else. I'll give that a shot tomorrow and see how it does.I would recommend taking the power commander off, best way to check if its your bike or the power commander (even though it does take time to take it apart). From there it makes it easier to see what's causing the problems.
It could be but I doubt it. 2wheeldynoworks said the exhaust was most similar to the M4 pipe and reflashed the ECU to match that. The power commander was also running the M4 tune but I tried a few others including the arrow exhaust with the baffle removed. I figured that tune would make it run rich but it changed nothing.Running too lean perhaps?
I haven't felt any surging. Any idea how I can test the AFR while it's under a load? Thanks for the help.It's hard to tell by sound, but it does sound like leaness. Does the bike surge when this is happening? I'd stiil get the AFR checked at light load.
