Carburetor Inlet Note: This manifold is designed for large performance carburetors with a 36mm spigot mount (Keihin PWK, OKO, Stage6 flat-slide). It will NOT fit stock carburetors or small-body Dellorto/Arreche clamp-on units without a step-down adapter.

Off-Road Use Only: This product is not intended for use on public roads or land.
Mechanic's Tip: Test your carburetor angle through the full range of rear suspension travel before finalizing position. Compress the rear shock fully to ensure the throttle cable or air filter won't contact the frame or helmet bucket over bumps. Torque base bolts evenly to prevent vacuum leaks at the reed block gasket.
