Swingarms

Are the 82 and 83 swingarms interchangeable, only picked up an arm at a motojumble that was labelled as an 82 but it was white and looks identical to my 83 CR250 ?

Well yes they both will fit into the frame and engine the same. Isn't there a length difference just between models in the same year. The silver frames have the shock mount significantly farther from the swingarm pivot than the white ones. I doubt the silver ones and the white ones have the shock mount in the same spot. I don't know about how used parts prices are lately but a complete swingarm with good bearings and race on one side used to cost less than the bearings and race thing which looks like a piston wristpin. It seems for 1984 or there abouts they added a nut near the axle on the chain side so the chain forces are contained from both directions, that would be the one to look for. It isn't just in the used parts at swap meets and ebay where there are errors about years and fitments.

It looks identical, but i will measure all the critical features first.

Yes you can mount them up but the shocks won't fit (different length/angle/ratio) I'd pass
