I currently have a stock cylinder 370 long rod engine and was considering making the jump to a cub cylinder setup. I Just rebuilt my crank so I'd like to stay stock stroke with the 115mm rods. My current cylinders are at 66mm and need to be bored to 66.5mm, which is the max bore size. I was thinking I could instead run 68mm cub cylinders. I still have a stock cylinder head(un sure if any work has been done to it,looks stock). I also already have 35mm pwk's, in frame drag pipes, v-force reeds. My stock cylinder and cases are ported for the 370 setup(pretty aggressive, no low end). Everything should swap over to the cub cylinders? Is it worth the money? or is the power gain not gonna be much? Where is a good place to buy the cub cylinders? I only ride the bike at the dunes and do a lot of hill shooting.
