Good To Know
Q: Do I need to rejet the carburetor after installing this top end kit? A: If the bore or compression differs from stock, carburetor jetting may need adjustment to keep the air-fuel mixture correct. Q: Is machine work required before assembly? A: Check piston-to-cylinder clearance and ring end gap during assembly, since tolerances can vary between kits.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
