Product Overview
This is a brand new, genuine Yamaha factory replacement carburetor O-ring. In vintage ATV carburetors, these small O-rings are critical for maintaining the correct air-fuel mixture. Over time, exposure to modern ethanol-blended fuels causes original rubber O-rings to shrink, crack, or harden. This leads to difficult starting, "hanging" idles, or persistent fuel leaks that can be both a performance issue and a fire hazard.
Why Choose Genuine Yamaha?
Carburetor tolerances are measured in microns. Aftermarket "universal" O-ring kits often use generic rubber that swells when it comes into contact with gasoline or doesn't provide the exact seal required for Yamaha’s specific Mikuni carburetor bodies. This genuine Yamaha part is made from fuel-resistant Viton or high-grade Nitrile to ensure a perfect, long-lasting seal.
