Moose Racing Top End Gasket Kit – Yamaha TW200 / TW 200 (1987–2024) – Complete Top‑End Rebuild Set

OVERVIEW

The Moose Racing Top End Gasket Kit delivers every seal, gasket, and O-ring required to perform a precise top-end rebuild on Yamaha engines. Built from durable high-tech gasket materials and featuring OEM-quality oil seals, this kit restores critical combustion boundaries and eliminates recurring fluid leaks after extended service life. Specifically engineered for the Yamaha TW200 platform, it serves as a complete solution for routine maintenance, bearing replacement, or fresh piston installs.

ENGINEERING & PERFORMANCE

Precision-cut to maintain stable cylinder pressure, this gasket set seals combustion chamber interfaces while resisting heat degradation across repeated thermal cycles. The reinforced base, head, exhaust, and tensioner components distribute clamp load evenly to prevent local stress failures and gasket extrusion. High-reliability rubber and composite hybrids withstand continuous exposure to synthetic oils, coolants, and elevated operating temperatures without premature hardening or shrinkage. Direct replacement dimensions match factory bore-to-bolt clearance, ensuring straightforward reassembly without drilling, trimming, or adapter spacers.

WHY RIDERS CHOOSE THIS

Mechanics and enthusiasts rely on this kit because it consolidates every mandatory top-end seal into one organized package, removing the guesswork that often leads to cross-threaded bolts or missing O-rings during teardown. The premium gasket compounds and matched-oil-seal ratios lock down compression zones efficiently, reducing blow-by and supporting smoother throttle transitions right out of the carton. By addressing valve guide wear with included valve seals and reinforcing the timing-side and exhaust pathways, the set extends overhaul intervals while preserving factory power delivery. Its exact TW200 application guarantees correct gasket thickness and bolt-hole spacing, delivering a trouble-free job that holds up under trail riding and daily workshop conditions.
