I haven’t touched the idle screw on the carbs. This happens with no choke and the motor warm. Funny thing is last time I checked the carbs for leaks, I put my finger over what I assume is a vent (it has a hose that connects it to a black box on the left side of the bike) on one carb and the idle slowly returned to normal. I’m going to get FCR’s as soon as I can, but in the mean time I’d like to ride it. I’m going to recheck for vacuum leaks this weekend. I’m also going to try and sync the carbs the best I can.
