Description: - The crankcase is the structural heart of your engine’s power, and our components are manufactured to the highest tolerances for the Yamaha RayZR. This comprehensive kit features the crankcase 1 and crankcase 2 units, joined by a high-grade gasket and pin dowel for an oil-tight fit. Internal pressures are managed by the breather and pipe, supported by element 2 to ensure proper motor ventilation. We provide all essential seals and plugs, including the plug oil, plug oil level, o-ring, and oil seal, ensuring your internal gears remain lubricated. The addition of the internal cover 1 and cover 2 units, along with the gasket crankcase cover 2, provides extra protection for your drivetrain. Every bolt flange, bolt, and plug straight screw is engineered to withstand extreme thermal expansion and mechanical pressure. These original parts offer the technical clarity and purchase confidence required for a total engine rebuild. Trust in the integrity of original components for the long-term service your machine deserves throughout its life on the road.
