what type and size carb comes off a stock 88 250r? and what would be a good replacement, the only mods is a pipe and v-force reeds? thanks

 

34mm keihin PJ is the stocker

People normally replace it with a keihin PWK Airstriker 38 or 39 mm depending of what you're going to do with it

 

take the carb of your cr250...lol
we took the carb off an rm 125 an put it on my buddys lt250r
i am almost positive that the 125 dirt bikes carbs are all 36 mm pwk and the pwk's are a way better carb than the pj's
not sure how big the 250 dirt bikes carbs are
