WM, If you've got the time, click on "Rebuilding a 92 R100GSPD" in my sig line.

Venolia 1050 pistons mated to modded '77 R100S "squish band" heads at approx 12:1 (measured pressures, not cc'd). Torque, mid range power and fuel efficiency are all up by significant margins.

Now if only I could find a way to control distorting cylinders that have been bored too thin to maintain dimensional stability...

It never ends.
