easy remove the head and remove the valves, take i to a local place the deals with shaping steal, get them to shave the underside of the head about 8thou of an inch. then when puting the valves back in buy harder valve springs. when its all back together buy a racing sparkplug. if you want, get the fuel lines in your carby boured out. with all that you will probibly sit on 130kmph
