On high compression motors with tight tolerances 32:1
You can run 40:1 on a rec boat with mild mod compression.
I personally run 40:1 on my Stage II GPR. 150 psi compression, no porting. At my 100 hours inspection, everything looked great ! Piston skirts, powervalves, cylinder walls ect.
Keep in mind also> !
* The OEM oil injection is set to run 32:1 at W.O.T.
Also use a good oil such as Amsoil

I can't find the powervalve pics just yet, but trust me, they looked PERFECTLY CLEAN !!! no gummy deposits or carbon buildup!! I was amazed !!
When we installed cajundude's gas valves a couple of years ago, he had 85 hours on the motor [Amsoil]. His too looked extremely clean.
My piston skirts at 100 hours had no scratches at all.
I expect to get atleast 300-400 hours out of my motor by just doing rerings every 100 hours for a peice of mind.
Amsoil is da'bomb
