welsh pitbike 140cc carb
hi i have a 140cc welsh pit bike iv recently fitted a 1/4 nibbi throttle but now iv noticed if i blip the throttle from idle or go straight to wide open the bike goes to die.
iv tried to adjust the air/fuel screw and tried all possible needle positions with no joy
other than this the bike starts, idles and rides fine any ideas ?
iv looked at a nibbi 26mmPE but im not sure if this is this issue ?
