The 83+ has 4/110 hubs and the 81-82 has 4/130 hubs I believe.
The 84 has little higher compression then the 83.
83-84 had a different port design to I think.

 

BIGRED,

The 1981 had those 2 piece wheels with a 3/100 bolt pattern like the early 110 and 185.

I don't have anything on paper regarding it, but I believe you are right about the 4/130 on the 1982 model. I do remember it being a 2 piece as well, but I can't remember the bolt pattern myself.

I'll try to do some more digging.
