K krusty1 Member Mar 7, 2010 3 0 Mar 8, 2010 #1 I have read in a few of the older threads, that if you shave the head .020-.040 of an inch you can get the compression up to around 10:1. Can anyone tell me exactly what lip has to be shaved off? Is it on the cylinder or the head shell?

K krusty1 Member Mar 7, 2010 3 0 Mar 8, 2010 Thread starter #3 I don"t really want to mess with the port timing, I figure if that needs to be done, then I will do it with the piston skirt and transfers
