Piston & Cylinder set for KE21V

This Kyosho 74035-03 Piston & Cylinder Set is an RC-scale replacement part intended for the KE21V engine family. It provides a direct swap option when the original piston or cylinder shows wear, scoring, or compression loss during routine maintenance of nitro R/C engines.

Use this set as part of standard engine service: remove the head and crankcase per the engine manual, inspect the crankshaft and bearings, clean mating surfaces, install the piston and cylinder with proper alignment, and verify compression before running. The component serves a maintenance and tuning role rather than performance upgrades, helping restore factory compression and prolong engine life.

The set is aimed at hobbyist service and track-side repairs where a known-fit replacement is preferred to improvised repairs; always use appropriate gasket seals and follow the engine manufacturer's break-in and tuning procedures after installation.

Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.
