Keihin PWK 38mm Air Striker Carburetor For YZ250 RM250 CR250 KX250 CR500 KX500
This listing is for a new Keihin carb that is pre-jetted so it will require fine tuning according to the machine you have, any modifications, and altitude. Some spare Jets are included to help. If you need any help with recommended jetting specs feel free to message me at anytime.
