EDIT: meaning ... did you inspect the cam journal to see if it was worn. The side by the cam chain gets the most abuse, and if the oil was crud, then maybe the journal got worn and has slop..... Let me know if you need a photo, I have a head in the garage that has a worn journal....

I've ran it only a couple of times, about 10 to 20 min's each.

Interesting point, turning the engine backwards does engage the starter as we all should know, but I also hear a kind of chain scrapping noise on the case, same area.

pop the starter and do it again.... it would be interesting to know if the scrapping noise continues...

Haven't taken anything apart yet cause I didn't have time.

Last chance for blind diagnosis.

Started her up, cold idle knock almost gone, rev her up and it's there.

Went and got mechanics stethyscope and started up the 96 for comparison so you don't need to know it whirr's the same all over.

But the knock, knock is loadest.... drum roll please... in the middle of... the cylinder. Same knock all the way around.

BTW: HF has stethyscope's, when they are on sale, only a couple of buck's. And it really beats a screwdriver hands down IMO.

So last chance to make a guess before I tear into it.

It was painful, but I had to vote rod myself. It's really hard to vote without hearing the actual sound, but I can spot piston slap a mile away.
Had a rod blow on my '84 Sportster, not a pleasant experience. Before she blew, there was a very distinct slap, almost like a mini sledgehammer hitting led. When the rod blew, it was like the bike was running out of gas. She lost all power. Got it home, and then to a mechanic friend of mine who was also a machinist. After he replaced the rod, he said that cleaning all of the metal bits out of the motor and oil system took longer than the install itself. The key is to catch it before it blows.

Looking for an impact driver to get some screws off that looking kinda permanent. Good reason for a ride But It's my b'day, going to visit my folks for a couple of days.
