hmm. This is wierd. The frame is an 81' or 82'. It has the special coolant passage through the frame with fittings for the hose under the tripple tree. (83'+ didnt have that). The engine is an 82'. It has a more square cylinder with a head thats flat on top (minus the bolts, spark plug, etc.) and the coolant hose goes into the back part of the top of the head (81' it goes in the front). And finally, I have the 82' swingarm (not v-shaped like 81' and the "bottom" of the shock is mounted higher than 83'+).
So I have come to the conclusion...I have an 1982 YZ125.
And yes, its pretty clean. Has a new top end, all plasctics are intact and not beat up, newer tires, new sprockets an chain, etc. I think I got a good deal. I just need to find a clutch basket....which might be a challenge. And about the blue...that wont last long....kinda reminds me of a suzuki. Im painting it black again.
