Default Re: Curious about the engine, :question:

This is even more confusing maybe. If the ZAF80 uses the short piston then it must have a taller rod. Im thinking the 80 may designate the 114mm rod. If the ZAF50 is 110 on the rod and uses the tall piston then its the half breed will be .062 in the hole. A ZAF50 with a short piston would be so far in the hole it might not run.

I think.
