85 atc250r

Picked up some 250r stuff, not sure why it was a good deal off a guy who knew me. Sold some of it bought some more.

1985 Honda atc250r with 86 250r rear end...motor, none prob blow in a wr400f motor or 426f as they are fun and plentyful.

I'm not 2 stroke guy anymore, not after todays 4strokes.

$30 yes. Guy never payed for his work and it sat at the shop upnin the barn for 5 years. I paid my buddy for it. It's gonna need opened up cuz I'm sure rings are rusted to cyclinder. It's taller then the 250r motor so lowering frame rails will have to happen.

Water jetted some reinforcing rings to weld in my ltr450 rear rims and welded in 3/8 aluminum bar stock to my front rim to stiffen it.

Brakes used were trx450r rear full assembly. 700xx front master cylinder since part number was same as trx450r but 1/3rd the cost.

Cutting frame up next for mods.
