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

Service screw set for KE21V powerplant

The maintenance screw set is intended as replacement hardware for the KE21V engine found in radio-controlled vehicles. It serves as a practical spare parts option so tuners and mechanics can remove and replace fasteners during service or tuning sessions.

Note that compatibility is limited to the KE21V engine as indicated, and the screws are meant as engine-specific accessory hardware rather than general-purpose fasteners. Use the set during routine maintenance, inspection, or when preparing the engine for tuning work.

In tuning terms, the set supports consistent results by ensuring fasteners are in good condition for accurate component alignment and reliable reassembly after carburetor or head work. Tighten screws evenly and avoid over-torquing to protect engine threads.

For model owners running a KE21V engine, this maintenance screw set keeps service and tuning activities uninterrupted by providing direct replacement hardware.
