I´d like to need up the top end for more power ( torque) & throttle response. Upgrade the cam shafts , valves , valve springs, timing gear & chain & possibly piston heads to. I´m already going to have it apart so it´s definitely getting new tougher rings because it may end up with a turbo at some point lol. Worth doing? Thoughts ? It´s going on a buggy/go-cart .
