80in Shovelhead Cylinder Q

My neighbor has a nice early '80s FLH, the rear cylinder has a bad spot about halfway up the stroke that looks like a ring has rusted to it at one point. it catches a fingernail and is about .5" long. Lots of blow-by on leak check he says...

Can he just get a new cylinder and rings or are there other considerations that I don't know about.

Best sources?

It might even only need a honing and new rings instead of a rebore and piston.

Anywhere you can go to get it checked out?

I'd only waste my money if I didn`t spend it on all my bikes......

Any good auto machine shop should be able to help you out. At the very worst you can have it sleeved.

Assuming the front cylinder is stock bore, you can get a new cylinder with a fitted piston. Or bore both OEM's.
