I have a Question about a Odd Cyl. Wear Pattern on a cyl. from a KEC440/21 engine. I'm disassembling & cleaning up the parts for storage of a KEC440/21 ( Reed Valve ) engine, I honed the cylinders to grease them up so they don't rust in storage, after honing one of the cylinders I noticed that this cylinder is wore in between all the ports?? ( between the all transfers & exhaust ) the hone didn't even touch this part of the cylinder?? (about 1/2" to 3/4" in height)
I've never saw this before on any engine & if I would have been using one of those cylinder hones with all the little balls I probably wouldn't have noticed this??
Any Idea of why all this wear in this area??

Could a ring with carbon build-up underneath do that?

Well, it can't wear IN the port, so that's the only contact area that is left.

Question about Odd Cyl. Wear Pattern
But why only in that area & not above the ports also?? I was wondering about a badly machined liner bore, a little to wide at the bottom, that would make the piston move/slap more at BDC & therefore causing the rings to wear the cyl. at that point??
I'll clean the grease out of the cyl again & try to get some pictures.

Well It is one of 2 ways, either everything looked good on that side.. or it was the other side & was at BDC & was stuck so bad 
I had to pound it out even after days of soaking.. 
oh yea I forgot to mention the mouse nest that was from the top of the piston @ BDC to the top of the head... Thus why the piston was stuck..
