i just opened the carb up and the main jet is 250 and im going to the store now to get a screw driver for the pilot cause i dont have a small enough one. the carb he said is a 30mm mikuni carb and i have an fmf exhaust, and bored .60 over. does a 140 main jet and 40 pilot sound good or no?

Thats strange because i have a fmf exhaust with no airbox lid, and a 30mm carb and im running a 155 main jet? And i did i plug chop and my plug was brown(thats a good thing)

well its because i just bought it and the kid just got a new carb (30mm mikuni) and it had the jets in it that came with it which was the 250 main jet and the pilot was actually 40 so i just replaced the main jet with a 140 and it seems to be running alright.
