WHY RIDERS CHOOSE THIS

Riders choose this aluminum flange to permanently eliminate recurring vacuum leaks that standard factory components struggle to contain over time. The 1051/1052 alloy provides the necessary stiffness to maintain a flawless seal under heavy throttle and off‑road vibration, which keeps the carburetor running smoothly and prevents stalling in rough terrain. Because it drops directly into the factory mounting points, installation is straightforward and restores original carburetor spacing without cutting or modifying stock lines. Builders and trail riders trust this setup to deliver predictable throttle response and reliable cold starts on every outing.
