This is a steel curved manifold used to adapt a 22mm Mikuni to a Honda GX200 engine. The curved design allows for tire clearance in go kart applications and more leg room for mini bikes. Laser cut flanges tig welded to a tubing radius. Pulse fitting included to run a fuel pump. Email us if you'd like to get one without the pulse hole. Fits GX160, GX200, 212cc Predator and the other Honda clones.
