well ok i have a stock 86 250R with the stock munki carb, and right now i have it jetted for the atlitude. and in 1 month im going back to sea level whats the stock jets size? and should i get a 1 size up jet for the FMF pipe?

thanks!

 

I think 220 is stock. You definitely need bigger jets if you got a pipe. How much is a more difficult question.

 

what does everyone think of a 240jet for sea level pritty good starting point?
