Now it's time to play, "Name Those Parts"!

My son and I are looking for advice how to identify the manufacturer of aftermarket cylinders. We can't seem to find an OEM stamp or part numbers.

A friend gave us these "thick wall" slip-in 96MM cylinders that he says will slip into the 1.7 case without machining but of course it would require machining the 1.7 heads or upgrade to 2.0 heads.

At first, we were going to hold on to these, but it appears we may need to rebuild the 1.7, so we're thinking about building it up to a 2056. Before we get too far, it would be helpful first to know exactly which jugs these are so we can match with appropriate pistons, cam, crank and heads. The walls look to be in really great condition. No cracks or broken fins. May need a final polish and cleaning.

Look around the base of the cylinder where it joins the case very carefully for casting marks.

I looked extensively around the edges, base, fins, top and bottom with no indication of marks. I think these were ground off or aftermarket with the markets/part numbers on the matching piston set. I will try to verify if they are in spec for rounding and determine if I'll sell them or use them later. They appear to be in really good condition.

I'm going to "close" this thread. I was able to get some good intel from FB forums on 914s. Hope you enjoyed the pics here anyway.
