Have 2005 Z 570 have cleaned the carbs and has good fuel ... at low rpms sled seems to backfire and miss but if give more throttle catches back up and is fine... but when let off does it again any ideas thanks
Make sure the throttle position sensor is adjusted correctly, that will cause your symptoms. Adjust cable to activate the rear pin switch at closed throttle. The front switch must be open before the rear one activates..
