Just got finished doing a valve shim adjustment and lo and behold the bike started up! With my luck I thought it would explode
. Got it warmed up and adjusted the rpm to a little over a grand. When I goosed the throttle to about 4 or 5k it took several seconds for it to come back down and it stopped at about 2k. I proceeded to chase my idle but would hang high after blipping it or plunge to nothing. My main needles were filthy and the whole carb was cleaned. While it was apart I added 1 washer per side for a total of 3 per side. Also have not synced the carbs yet. I plan on going back to 2 washers and syncing but can there be another reason for the rpm to hang up? Thanks for any advice
