Comer C50 and K80 Ring Lapping Tool. This tool is designed to assist in preparing piston rings on the Comer C50 Kid Kart engine and the Comer K80 engines. These engines are common in the Kid Kart and Cadet kart categories, and the power train system relies upon tight tolerances for optimal performance.

With this tool you can finalize preparation of piston rings for these two engines, to ensure optimal performance.

The ring lapping tool is a singular unit - meaning there are not multiple pieces that come with it. Each tool is precision milled for optimal run out, and engraved with the PKT logo.
