porting help

looking for the/a post on the porting i can gasket match no broblem but what about the piston clearances and the ports in the jug i seen rase one and lower the other but i cant find the post after searching

From my personal experience i wont be changing the port timing again only opening up the port lengthways only. I raised the Exhaust and lowered the intake ports about 2 mm each.

Down low it was a dog even with a 44tooth but once it started reving and reving it went faster than std but not worth the loss of low down torque. It you find a way to make more down low power let me know.
