Piston and cylinder replacement for KE21V engines

The Kyosho 74035-03 Piston & Cylinder Set is supplied as a replacement item for the KE21V engine series. It is intended to replace pistons or cylinders that have worn or lost compression after extended running.

Fit the set as part of normal servicing: remove the cylinder head and crankcase per the KE21V guidance, check the crankshaft and bearings, clean mating surfaces, fit the new piston and cylinder ensuring correct alignment, and verify compression before use. This replacement is aimed at maintenance and basic tuning tasks rather than performance enhancement, helping recover factory compression and improve engine longevity.

Designed for hobbyist workshops and pit repairs where a verified-fit replacement is preferred, always use the correct gaskets and observe the engine maker's break-in and tuning instructions after installation.
Remark :
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.

Is this an aftermarket or original replacement part?

This listing is for a replacement piston and cylinder set intended for KE21V engines. It is supplied as a service replacement rather than an original equipment designation.

Will this restore compression if my engine is underperforming?

If compression loss is due to piston or cylinder wear, replacing these components should restore compression, provided other internals like the crank and bearings are in good condition.

Any special preparation before fitting?

Ensure all surfaces are clean, check bearing play, use appropriate seals, and follow the recommended break-in routine after assembly to achieve correct seating and operation.

Can it be fitted track-side with basic tools?

Yes, with basic engine service tools and a tidy workspace it can be fitted track-side, but confirm compression and perform a brief break-in before full racing runs.
