Description: - Harmonic precision is the focus of the RayZR B2UA Camshaft & Chain assembly. This top-end technical kit features the high-performance Camshaft Assy 1, supported by high-speed Bearings and a precision-engineered Sprocket Cam Chain. To maintain exact timing, the assembly includes a durable Chain, Guide, and the Tensioner Assy Cam Chain with a specialized Gasket Tensioner Case. Silent and stable operation is managed by Stopper 1 and Guide Stopper 2. Every technical hardware piece, including the Nut Lock, Plate 2, and various O-Rings, is included to maintain an oil-tight and perfectly timed head. By using genuine Yamaha internal timing components, you prevent the catastrophic valve failure associated with low-quality chain drive systems. This is a storyteller of internal perfection, providing the purchase confidence and clarity of a factory-calibrated timing set that ensures your machine remains quiet, efficient, and responsive for the long haul, maintaining the smooth power delivery you expect from Yamaha’s engineering.
