Man I like this forum; thanks for all the advise!! To late for not starting smoking. I started at 17 and stopped at 45 (hardest thing to stop and cold turkey worked for me after 5 years of trying).
Yes, rings installed right. No, I didn't hone and this could be my issue, but I think it was blowing oil before I got it, so I doubt the hone was it. I had the heads done at a shop and I feel certain it was done right. I bought a top-end gasket set that included new unbrella valves. Think I will tear the front cylinder down again and inspect the rings and ring grooves, then hone and reassemble. If that don't work I think I'm done with the cylinders; I think .030 over is as far as you can bore based on what I see in the manual. I'll buy new cylinders and pistons. Thanks again!

what type of ring, cast iron, moly, chrome???? It won't hurt as long as you have it apart to check the rings to insure the gaps are staggered and right side up. It is easy to get one in upside down (don't ask how I know) but it's a mistake you only make once!!LOL!! Not honing the cylinders can make an engine smoke and make the rings just about impossible to break in. Take a look in the ports at the valve stems, if they are wet you found your problem.

Looks like your experience may be on the money. Tore it down and sure enough I had the second compression ring upside down. I turned it over, went and bought a hone and honed the cylinder. I'll by new gaskets this week and hopefully have back together by soon.

Anybody that does any number of engines can have this happen. After the first time of doing this when perhaps you were distracted. Then you double check them every time just before you put the cylinders on. Make sure you wash the cylinders out with hot water and dish detergent until you can wipe them with a lint free rag and they come clean. Them wipe them down with a little ATF fluid so they don't rust. Hope this helps.

So now you know ... Never replace rings without at least honing the cylinders to get a good seal and be very careful when you hone the cylrs. Follow the directions exactely and with what you have already done , you will have a new motor .
FYI ... if you havent purchased an official Harley shop manual , do it now .
