Did a topend (rings, honed cylinders, gaskets, carb, oil lines,) last year after getitng back from my deployment. Now I got black smoke. I know it runs a little rich but it started to knock and last week on the way home the knocking and ticking got worse. A couple of weeks ago I did a compression check and the rear had 106, and the front had 105. I left it there over night and had 96 in the front in the morning (about 9 hours later). Yesterday when I decided to come out of my non riding depression and not shoot the bike I started it up and put my hand a few inches behind the exhaust. Smelled my hand and yep, smelled like oil. If I have compression, or maybe not, how is the oil getting out the exhaust? Could it be the oil seals? Would that make that much difference? I replaced them too when I freshened it up. I have to take it all apart again because the rear base gasket is leaking like a sieve also. With a limited budget and the bike paid for a long time ago, I'm looking on keeping her going until I can retire in a year and get a good used cop bike. Any help would be better than me smacking my self on the head with a ball peen hammer (again). Thanks

Did you replace the valve seals at the time of the re-build??
How many miles on your lifters??
Reason I ask, is that a service bulletin was issued from the Moco, in regards to "inspect/replace" them @ 25,000 miles.
Cometic gaskets will solve your cylinder base leak, generally.

I replaced the valve seals but not the lifters. In fact I looked at the valves one last time before I put it all back together and noticed one of the keepers was on wrong. The bike has 79,000 original miles and as far as I know that is the first time it was opened up. I got it when it had 40,000. I put this thread on touring models forum also. This is the first time I have gone this far into an engine. I replaced the cams on my wifes Ironhead. and have done clutch work to it also. On my FLHTC I have replaced the belt, the clutch, the stator, wheel bearings, neck bearings, that is another issue, still have problems with that.) So I am learning everytime I do something. Thanks.

If I had the funds I would get another motor and do just that. I know about sending mine in the HD and getting it back like new for what 1,800-2,000 I think. I have some pics of the front and rear spark plugs. I had turned the top screw a little on the carb (clockwise) because I knew that it was running rich. The knocking is in the last two pics. So now, to me anyway, the front spark plug looks o.k. The right portion on the back plug looks like what it did before but before you could barely see the electrode it was so bad. They both look cleaner than what they did after looking at them three weeks ago. If you look above the chain on the next to last pic there is a line and a little nick right before that one. No thats not a shadow. Thats a gouge from the chain. Hope that was where the knocking was coming from and the last pic shows how bad the chain was loose. I have a new shoe for it so that is going in as well as adjusting it. Still leaves the heavy oil consumption and the smoke. Still working on that part.
