Piston & Cylinder Service Kit for KE21V - Kyosho 74035-03  [KY-74035-03]

KE21V engine piston and cylinder service kit

The Kyosho 74035-03 Piston & Cylinder Set serves as a matched replacement for the KE21V engine series. It is intended to replace components that show scoring, wear, or reduced compression after extended running.

Use this kit during routine overhaul: follow the KE21V service procedure to remove the head and crankcase, inspect the crankshaft and bearings, prepare mating surfaces, install the piston and cylinder with proper alignment, and confirm compression prior to use. This kit supports maintenance and conservative tuning rather than performance boosting, helping return the engine to factory compression levels.

Geared toward hobbyists and pit-side repairs where a reliable replacement is preferred, always fit appropriate gaskets and adhere to the engine maker's break-in and tuning recommendations following installation.
