I am looking for a little help. I pulled my bike apart last year to powdercoat and polish everything. When I took the motor out, it ran great. I have just re-assembled the bike, and the only changes I made were switching from Stage IV pipes and stock CDI, to CPI in frames, and a Dyna. I bumped the main up from 152 to 155 (35PWK's) and left the needle and pilot where they were. I can not recall the needle position, but the pilot's are 58. It fired up on the third kick, and ran fine while warming up. Once warm it idles smooth for about 10 seconds, then drops down and runs rough for about 10 seconds, then back up to a smooth idle. If I let the bike sit, it will continue to do this. The timing of the up and down is consistant. Throttle response is fairly crisp (just running in the garage), but it does hang up for a few seconds after revving, before it settles down. I know that is typically a sign of lean, but I have not experienced the surging before. My thought was a float out of adjustment, but I checked them both, and they appear to be on the money.
Any thoughts?
