R60/2 oversize piston
Bench Mark and Salis both have 73.5mm and also up to 74mm
Salis $154.00 x 2=308.00 plus 40.00 shipping
Bench Mark 199.00 x 2= 398.00 plus shipping
As you allready know Bench Mark is a liitle higher here but their tech support is worth it wait in gold

I don't believe that the
My friend is probably focusing on getting the heads/cylinders/headers off first. We had discussed an approach to rotate the engine about the front engine mount to such an angle that the transmission could be pulled off and out. Then we would man-handle the case out of the frame. He has already received the shipping box from Vech so he's headed to getting the case into that box for shipping back. I'm just providing help when needed. I've at least done this once before when I did this on my R69S, so at least there is some experience with this process...albeit limited!

Pistons
The cylinders are not bored on a taper. The pistons are a little bigger at the skirt than at the ring area, but not the cylinders. To assess weather or not to bore the cylinders for the next oversize pistons, more accurate and multiple measurements will need to be taken with a bore gauge, or at the least a set of T-gauges and a micrometer.

removal of engine and gear box

I removed the front engine bolt loosened the rear then tilted front of the engine down and then remove the great box
Guess it may also work if you removed the rear engine bolt then also tilted front down to remove the gear box ??
