dont let people lie to you.
your gonna destroy a few cylinders, and waste a bunch of time, bolting them on and off to see that they dont work. then youre gonna hate everyone and everything. when ya could of just bought ported cylinders and been out riding instead of fucking around.
best thing you can do, is get some ported cylinders, degree wheel, dial indicator and copy that shit ! then make changes to see/feel a difference.
but your not learning how to port a 2stroke, ya just copying.
