Bart (and the other shops) that do the high compression pistons use a modified C-85 piston. I can't remember what the compression ratio ends up being, but I thought it was 9.1. Maybe I am getting that number mixed up from something else...
They also do some work on the ports as well.

Bart flow-matches and balances, cleans up any geometry problems, and then adds 9:1 pistons. I completely believe 115-120 hp. I had to add 4 inches of additional prop to prevent over-rev problems. It was stronger, faster, and as a bonus, cooler than before. R

I have always felt the supercub is one thing mankind got right the first time but that there were better materials and methods to build them. CubCrafters products are proof I was right.
All this begs the question: Why isn't CC offering the 0-200D instead of the 0-200A for the Sport Cub?
The 200D is lighter, can burn mogas, and with 8.5:1 pistons should be peppier with more horsepower...and less expensive out of the box when one factors in the additional cost of converting the 200A.
That doesn't preclude Bart tweaking the 200D for the ultimate little hod-rod.
