I'm looking for a 38 - 39.5mm PWK for my CR500 and can't seem to find a resource anywhere that translates the main body numbers into the carb size. Here is an example of what I mean :

KEIHIN PWK "V398BI11"

Any info would be a big help.

personaly id buy new, trying to jet worn out junk never ends well

I agree with you on that. Most of what I'm looking at is coming off newer bikes (mid to late 90's) that people swapped out the carbs on but I have no idea what a 98 KX250 or a 2001 KTM 300XC came with.
