Does anyone make an aftermarket piston for the 650L that is rated at about 9:1 compression? Stock is 8.3:1, kind of weak. All others I have found are 10.25:1 and higher.

I don't know of any either. I'm thinking to rebuild with a stock piston and have the head shaved a bit or go with a J&E 10.5:1 and have the crown shaved to reduce the compression some.
