Motobecane av10 Autisa 46mm "70cc" Cylinder Kit main Threads in and says MotobecaneVintage 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
