There is a gear on the RHS end of the crank that drives the clutch (primary gear) as well as the cam chain. According to one of the RC Cup racers this gear needs to be tightened regularly if the bike is being raced. Apparently, it comes from the factory with insufficient torque on the nut. If it backs off, the engine starts making a ticking sound before anything expensive happens. Drain the oil, pull off the RHS cover and the nut on the gear is right there ready for your socket and torque wrench. parillaguy
