Ray i have been wondering about what the right pinch might be for my particular motor.
To me the 'medium' is the highest level, and so part of my brain says that's the better option.

Another part of my brain says that perhaps a light-medium might be better for longevity or perhaps one more resizing after this one (if the first reconditions ok).
Your will be a better judge i am sure!

One thing for me is i think they dont make any new pistons and sleeves for my Nova Mega Sx 12 re EV1 MS anymore, so once it's done ... it's done!

I also wonder with all the different sets you have done if there is a similarity between sleeves and pistons from different manufacturers. Like roughly how many different sized sleeves are there for the .12 sized motors?

I am kinda hopeful that one day i might work out what other pistons and sleeves may work in this motor of mine.

Cheers~
