Description
The WSM Original Series Top-End Rebuild Kit is a dependable way to refresh the top end on Polaris 800 Virage-777 (All). It is built for real-world riding where heat cycles, sustained RPM, and on-water load demand consistent sealing and durability. This kit is configured for the application shown (verify bore size before ordering).
If your engine is showing low compression, hard starting, weak throttle response, or uneven power under load, a complete top-end service is often the most efficient fix. Using a matched kit helps reduce guesswork and supports consistent clearances, ring seal, and long-term reliability.
