Description

The Big Bore kit yields excellent results with stock cylinder heads.

Easy installation — no need to bore or split existing cases; simply swap the cylinders unless otherwise noted.

Cylinders are made from premium castings with cast-in iron liners for long-term durability.

The kit includes cylinders, pistons, rings and gaskets (head, base and exhaust).

Made in the USA. Project requires a skilled technician; it is the assembler's responsibility to check all clearances and assembly specifications. Not for Twin Cooled motors.
