Like moly grease? Your break in oil should be the same as what you normally run?

Are you sure about that. You can do that but if you what good ring seal and no piston wear then you what to run break in oil. I have alot of testing in this subject. Plus it even more important with a plated cylinder. Also most rings don't come lap for the bore there going into.

I was just asking brother. I wanted your opinion on what would be the best break in oil. Obviously the Amsoil Dominator synthetic would not be ideal IMO for assembly lube, but thats what I like for my premix oil.

kaw rider:
the amsoil dominator is made for short life race motors with no rust protection. For long life motor need to look some where else. When we ran amsoil we had crazy fast piston wear. A good semi-synthetic oil is good for long life motor. I buy it from a piston manfu. that makes break in oil for 2 strokes piston rings.

OK cool, while I have your attention, what premix oil do you recomend? I know to stay away from castor based oils for KIPS valve protection...

What say you sir?
