Interesting what you say about the pilot jets, because I'm fairly certain that the main jet is responsible for the wide open top gear seizure at over 11000 RPM, that's 180+ kph with the rear wheel locked and fishtailing round a slight bend!
Sorry. That was Power Jet, not Pilot Jet. You are right about it being the mains, but whether or not you retain the power jets will affect the main size.
