Awk,  any chance you can point me in a main jet range?  The bike is going to be running a unifilter, no lid, oil block off, stock carb(right now with a 230main) (32.5Pilot) , Stock pipe, and fmf powercore2, and it is now bored  .040 over to 67mm.    Im thinking at starting jetting and plug chopping at a 290main?    What you think?
