2002 XR50 Carb adjustments


Recommended Posts

I bought an '02 XR50 for my daughter. I need to do some fine tuning on the carb, and was wondering what both screws do before I start messing with them. Is one the idle and the other the pilot screw, and if so which is which? And lastly, does anyone know the factory settings (how many turns out)?

The one on the right, which should also be the only philips, is your throttle stop (idle) screw. The one on the left is the air screw. It should be adjusted about 3/4 of a turn out from "all the way in" position. This is the stock setting with the stock pipe. Idle should be set according to how the bike sounds........use your best judgement.... 🙂
