KE21SP Engine Service Replacement

The Kyosho 74031-04 Piston & Cylinder Set is produced for the KE21SP engine to serve as a correct-fit replacement when components show wear. It is a practical choice for workshops and hobbyists carrying out routine engine servicing.

Key Advantages

This kit is manufactured to match KE21SP tolerances so the parts sit correctly and minimise fiddly adjustments. Installing fresh internals helps maintain predictable throttle response and reduces the risk of overheating caused by poor compression.

Installation Notes

Make sure the crankcase and related parts are clean and free from grit before assembly. Apply recommended lubrication to the piston and check gasket surfaces; recheck compression after the initial running session to confirm a proper seal.
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.

Can I use this set with aftermarket carburettors or exhausts?

Yes, the piston and cylinder itself is compatible with typical bolt-on performance parts, but check clearances and tuning after fitting any aftermarket components.

What signs indicate poor piston seating?

Symptoms include high oil consumption, reduced top end, or rough idle. A leakage test and compression check will confirm seating issues.

Do I need specialist tools to fit this set?

Basic engine tools and careful handling are usually enough. Avoid forcing components and use proper cleaning brushes and light oil for assembly.
