1974 Z50 piston and jug

Replaced a scored cylinder and piston with a kit from "ECCPP".

Question, I am pretty sure the old piston came flush to the top of the cylinder bore.

This kit brings the piston up a 1/4" short of flush.

Yes, the cylinder is fully seated to the crankcase.

.. A problem or not?

I’m pretty sure that setup is for a late style motor…with that setup you will have very low compression and the motor will have no power if run at all?
