Motobecane av10 Autisa 46mm "70cc" Cylinder Kit main x1 25 x 40 xVintage and long discontinued 46mm av10 kit by Autisa. This is only for av10 engines. Seriously cool port map with stacked transfers and auxiliary exhaust ports. This looks like a real ripper! Aluminum cylinder and single ring piston. These are very old inventory. They may not be as pristine as a brand new kit. There might be dust, a wrinkle in the gasket, etc. No returns on these kits. Limited stock. We recommend chamfering and dressing the ports
