High-performance camshaft from Cardinals Racing V65 Yamaha / Minarelli YI-5 Engines

The Cardinals Racing V65 camshaft is a racing VVA camshaft. According to the manufacturer, it is compatible with all models equipped with engines manufactured in 2025 or later. It directly modifies the valve train control and is designed for sport-oriented engine setups that require altered valve lift and cam characteristics.

Compared to a stock camshaft, a racing version can alter the engine’s rpm response and power delivery in the upper rpm range. The camshaft plays a central role, particularly in performance-tuned engines or those with modified intake and exhaust components. Replacement may also be necessary if the original camshaft shows signs of wear. Typical signs include noticeable noises in the valve train, worn cams, or a noticeable loss of power. For installation, proper assembly, correctly adjusted valve clearance, and checking the timing are important.
