you could just go with a light bore kit(72,75,81cc) and keep the motor reliable. ive heard of the hi-c pistons blowing up, very esily.

full potential of the light bore kits isnt far off. i ran a 72 bore with stock carb and exaust and its perfect for a little more grunt. you also dont have to run race gas, that stuff adds up quick! if you can find a xr70 cylender, theres pistons around that work for the stock head.
