YCF Decompression Spring for YCF Bikes with ANIMA Engines (2024-2026)

The YCF Decompression Spring for Daytona ANIMA Engines is designed to support the operation of the engine’s automatic decompression system on compatible YCF motorcycles. This spring helps control decompression mechanism movement during startup to reduce cranking resistance and assist smoother engine starting.

Supports Automatic Decompression Function

Automatic decompression systems are used to temporarily reduce cylinder compression during startup. The decompression spring works alongside the decompression shaft and related valve train components to help the system engage and disengage properly during engine operation.

Designed for Daytona ANIMA Engine Platforms

This decompression spring is intended for compatible YCF motorcycles equipped with Daytona ANIMA performance engines commonly used in motocross, MiniGP, flat track, and supermoto applications.

Important Valve Train and Starting System Component

Small internal engine springs can weaken or wear over time due to repeated heat cycles and engine operation. Replacing worn decompression springs during engine service can help maintain reliable startup performance and proper decompression system function.
