So this is my dilemma: I have Quill slip-on pipe and a DynoJet Stage One Kit with a BMC air filter. The bike runs great at all rpms’ and I’m happy with the throttle response, etc. But when I go to adjust the idle and synch the carbs, the used-to-be-before-mods smooth idle drops like a rock. Its fine right up until I get the mercury in the gauges’ tubes all lined up and then the idle fluctuates constantly between 1100 and say 1250, and feels real rough. Sounds like it’s ready to die but doesn’t. Anybody else’s Niner do this? Any suggestions on how to smooth out the idle?
