I've used the race logic templates as well, I've also done alot of v-8 chevy porting. There is more to 2 stroke porting then you might think, your timing is greatly effected when you get into transfer port area. Don't get me wrong, a clean up helps and I like doing things myself but it is hard to get the power the pro's do. I had Jeff at F.A.S.T do a strong dune port, he does this stuff day in and day out. I have almost all the tools except the angle die grinder which was just about the same price for the port work. Good luck to those who try, my hat is off to you. :beer:
