Hi everyone, I ran across a post by Egor, and also had a friend mention this as a great mod. I am seeing and hearing that you can cut a little off the bottom of the piston skirt and it is supposed to change the timing and increase HP. Could someone explain how to do this and post pic's. Does the notched side go to the intake side or exhaust side? How far can you notch it? Thank for any info you can provide.
