I run the amsoil dominator oil. I have run it in this motor at 50.1 for over year now and still running strong and comp is still at 165psi in each CYL. Here is a link to it.

Just my two cents
Just checking to see if any one from HQ will be out at Pismo tomorrow? I will be there from 8am to 5pm for a day ride. I will be rolling in with a BLACK on BLACK Ford F250 and BLACK 24' trailer with 4 bike.
So when you say fresh hone. You just competed ring job on it? If so you my of not clean all the honing grit out of the CYL before you put it back together. Just a guess?
