My 1982 xr200r

[Hunter65]

Well i got this two days ago for 3 pounds of honey and 1 package of dear steak. i took it apart completely and the piston was missing a pretty good chunk and there was a lot of metal pieces in the transmission. Got that all cleaned out and now I've just got to get a piston and rings. Does anybody know how much horsepower this thing makes? I'm thinking that once i get it reliable that I'm going to paint the frame and get a stiffer shock for the back because its a little soft. Oh and the front shocks have an air nozzle thingy like on tires. I'm guessing that this is to stiffen the shocks with air. Does anybody know if this was stock on the xr200r?
