Might someone know about what jets I might need for a 38mm mikuni. I bought a dead pilot. I have come to the assumption that previous owner put a pipe new reeds, and the new carb. it is a flat slide style. he burnt the piston on the first ride. He said he had carb set up with jets for sea level and I do not think he ever actually tweaked it. so I am thinking he ran too lean and burnt the piston. what I do not know is what size jets do I need to have to be able to jet it properly. currently there is a main that says 350. which confused me because when I shop on line and I see much smaller numbers like 140 which is what is in my other pilot that has the stock kein carb. thanks.
