Keihin PWM 38 needle questio
Steven66 posted a topic in Jetting & Exhaust ForumNot specifically for a banshee but I figured I’d ask here anyways since banshee guys tend to know answers tuning questions. I have a PWM 38 4XL from a 1997 YZ250 with a needle that I can’t seem to find any information on. Most likely due to my lack of hands on use of Keihin carbs. The bike has a built engine with an old generation bills pipe that I have no actual paperwork on so the carb may have some wild needle in it that’s not normal for a PWM. The needle code reads N40G from what I can tell. Any info is appreciated.
