well i just blew my blaster up and now wanting to know whats the best piston ?

Ok ill have to get a leak tester and everything is coming along, i am getting the jug sand blasted then bored honed then put together leak tested and break in? How do you break it in and after that itll be ran like hell!!
 
Break in by doing 3-5 heat cycles.

Re torque the head and jug bolts, ride 2 tanks of gas at no more than 3/4 throttle, then grip and rip.
