Default 800 pistons on a 750 cranks

I keep seeing this question. I am not sure, but I think if you put 800 pistons on a 750 rod/crank you will in up with compression like a diesel.

Since the 800 crank in a longer stroke (66mm) the piston pin is set higher, to keep to dome lower and stop it from crashing into the combustion chamber. Put that piston on a 750 crank (61.5MM) and it will be about 2.25mm lower than before.

I see someone on eBay suggesting they will drop in too. Just depends on what you want.
