KE21V Engine Maintenance Screw Set - Kyosho 74035-09  [KY-74035-09]

Replacement screw kit for KE21V engine

This maintenance screw set provides replacement hardware intended for the KE21V engine in radio-controlled models. It is a straightforward spare-parts option so builders can swap out worn or missing fasteners during disassembly and reassembly.

Compatibility is limited to the KE21V engine as stated, and the set should be used as RC-scale accessory hardware rather than as general-purpose fasteners for other assemblies. Use these screws when performing scheduled engine maintenance, inspection, or preparing an engine for tuning adjustments.

The contribution of this screw set to tuning and upkeep is preventative: keeping correct fastener condition helps maintain component alignment and ensures reliable reassembly after carburetor, head, or crankcase servicing. Take care to secure screws evenly and avoid over-torquing to prevent thread damage on engine housings.

For hobbyists running KE21V-equipped models, this maintenance screw set offers a direct replacement option to keep engine service and tuning workflows uninterrupted.
