HVC Cycle has been providing parts and service to the 2-stroke community for more than a decade. Its latest new trick part is this Kawasaki H1 Intake Manifold Adapter Kit. Old carburetors wear out and the parts for them get harder to find. These adapters allow you to mount brand-new Mikuni VM round slide carbs to your classic H1. The original intake bores are oval, and the inside of this adapter tapers from the oval intake shape of the cylinder to the round shape of modern Mikunis intake boots. $175.
