Description

The Big Bore Cylinder Kit delivers substantial performance gains using stock cylinder heads.

Installation is straightforward: no need to bore or split existing cases—simply swap the cylinders unless otherwise noted.

Cylinders feature premium castings with cast-in iron liners, and the kit includes pistons, rings, and complete gaskets (head, base, and exhaust).

Made in the USA and intended for assembly by a skilled technician; always verify clearances and assembly specifications during the build.

Designed to fit Twin Cooled motors; confirm compatibility with your application before purchase.
