No valve oil seals so they can smoke a little.  Exhaust sounds odd.  Probably missing the baffles.

Engine and frame numbers never matched back then.  They were always off and sometimes by a couple of hundred units.

So you are saying these engines never had valve seals in them or they are just shot?? The bike is really loud in my opinion for those big pipes!

Never had them. 

It sounds like the baffles are missing.  Are they?

Later models have a one piece header and muffler with bolt on rear mount.  Early models had two pieces with a seal.  All had removable baffles.

It has a bolt through the end of the muffler, But I havent looked up there with a flashlight. Well....I feel like ive taken two steps back now. It running like crap again. Now the right cyl keeps cutting out. I was getting  black smoke at idle and it stumbled real bad until the throttle opened to about 1/3.... So I dropped the needles down one clip and that made it run a little better,  but its still not right. It runs like crap until you put a load on the engine and give it some throttle. Riding down the road it buckes, crackles and missed if you are just cruising but if you open it up, it smooths right out and pulls nicely until you let off the throttle. :( Grrrrr.

Jets are 140 mains, 42 pilots.... needles are 23...??? i think. Air screws are at 1.5 and slides are in sync. The jets are what was in it when I got the bike.
