KE21V Inner Head Overview

This Kyosho spare is the inner head component made for the KE21V engine and supplied as a direct replacement for RC engine maintenance. It locates inside the head assembly to form the combustion chamber and sealing interface, and is used during rebuilds, repairs, or when changing head components.

As an engine accessory the inner head influences chamber shape and sealing, affecting compression and stable running in RC models. When fitting a replacement, inspect mating surfaces and seals and confirm correct alignment with the head flange to retain proper compression and a reliable seal.

The item is supplied as a spare for the KE21V engine; always confirm part number Kyosho 74035-02 before ordering to ensure correct fit and avoid cross-compatibility assumptions.

Fit this inner head during KE21V service to restore head condition or support tuning work that requires a verified replacement component.
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.

How should I install this inner head on a KE21V?

Start by cleaning mating surfaces, replace any old gaskets, seat the inner head evenly on the flange, then torque fasteners progressively to avoid warping. Follow your engine manual for final torque values and sequence.

Are gaskets or mounting hardware included?

The listing refers to the inner head component only. Check the seller listing to confirm whether gaskets or screws are bundled before you buy.

Will replacing the inner head change compression?

Yes. The inner head helps define chamber geometry and sealing, so fitment quality directly affects compression. Verify alignment and gasket condition to maintain designed compression.

What checks are recommended before final assembly?

Inspect the head flange and sealing surfaces for nicks or residue, ensure gasket seating is correct, and confirm that the inner head sits flush before tightening hardware.
