Moose Racing 1003-0744 Carburetor Repair Kit 2002-2018 Yamaha YZ85

Restore Your Peak Throttle Response

If your bike is bogging, leaking fuel, or struggling to idle, it’s likely that ethanol-blended fuels have degraded your internal seals. The Yamaha YZ85 relies on a perfectly tuned fuel-to-air ratio to maintain its powerband, and even a slightly swollen O-ring can ruin a race weekend. This Moose Racing Carburetor Repair Kit provides a comprehensive solution, ensuring your fuel system is restored to factory standards. At Moto-House MX, we know that reliability starts in the carb, which is why we trust this kit for every OEM Replacement service we perform.

This kit is engineered for modern racing conditions, utilizing high-grade NBR rubber for all O-rings and gaskets. NBR is specifically chosen for its Heavy Duty resistance to the ethanol found in today's pump gas, preventing the premature hardening and cracking common in lower-quality kits. Every component is precision-machined to match Racing Performance specifications, including the needle, seat, and jets. By replacing your worn internals with these precision parts, you ensure consistent fuel delivery and a crisp, high-revving engine throughout the entire moto.
