First heat cycle down, started second kick. Larry's comp mod will be in my future I believe. For pre-mix I run my Amsoil dominator. On old cast sleeved cast rings you would not want to run synthetic, but on a plated cylinder with moly rings, it really does not matter what u run. Some don't out of old habit, but I have not seen any difference between one or the other on newer engines. Can't wait to see how she runs when I let her stretch her legs out.
