I've been using the 750 DOHC pistons with their shoulder turned off 1.5mm, about 1/4" in, with the K7/8 and F2/3 heads. It makes the CR about 9.2:1 on the F, and about 9.5:1 on the K7/8 head. I also mill the heads a bit, about 0.5mm.
At what bore size Mark?

No matter how many times you paint over a shadow, it's still there.
If you love it, set it free, if it stays it's probably one of my 750's.
