Review MAXPEEDINGRODS 83mm Cylinder Piston Top End Rebuild Kit Yamaha Big 1987 fits BEAR RAPTOR 350 1987-99

The Maxpeedingrods 9SWLG6 83mm Cylinder Piston Top End Rebuild Kit is an essential solution for Yamaha Big Bear Raptor 350 owners produced between 1987 and 1999 with worn-out or damaged engine components. This comprehensive rebuild kit consists of high-quality, aftermarket parts designed to restore your engine to like-new condition.

This kit includes several crucial components necessary for a successful top end rebuild. The heart of the kit is the new 83mm forged piston, which boasts increased strength and durability compared to the OEM piston. The piston features a low compression height and a honed skirt for optimal engine performance.

1. A compression ring to seal the combustion chamber and provide optimal compression.

2. An oil control ring to minimize oil consumption and ensure proper engine lubrication.

3. A piston ring to seal the piston to the cylinder wall for efficient power transfer.

The kit also includes a new set of gudges (valve guides) to ensure proper valve alignment and a smoother engine operation. These gudges are precision-machined to perfectly fit your engine.

Moreover, the kit includes new camshaft seals and intake manifold gaskets to prevent oil and coolant leaks. The camshaft seals ensure a tight seal between the camshaft and the engine block, while the intake manifold gaskets securely seal the intake manifold to the cylinder head.

Lastly, the kit comes with a set of new, high-performance O-rings to seal various engine components, ensuring a proper seal and preventing leaks. These O-rings are made from a high-quality, durable material to withstand the rigors of off-road riding.

In summary, the Maxpeedingrods 9SWLG6 83mm Cylinder Piston Top End Rebuild Kit is an all-inclusive solution for Yamaha Big Bear Raptor 350 owners seeking to restore their engines to peak performance. With high-quality, precision-machined components designed to provide increased strength, durability, and efficiency, this kit is an excellent investment for any off-road enthusiast.
