200x atc motor question

[ledofthezep]

What motors will fit into the 200x, like will a 350x motor fit, or even a 300x?

Reason I ask is my cousin has an 85 he's rebuilding. The rings are non-existant,...you'd think it was a freight train with all the damn smoke that thing blows. And the bottom end is trashed, primarily the tranny. Oh yeah, and the case is cracked by the sprocket, but doesn't leak...yet. So I figure it'd be cheaper to just get a new motor than try & fix that motor.

THanks in advance.:D

you would have to do alot of mods to get 300ex and 350X in their but a 185 or 200S motor will fit but its a auto and you have to figure out the brake peddle too

Cool, thanks a lot. That helps me out. I may have found him a complete running 200x for a couple bills...we'll see.:rolleyes:

a xr200r motor is a direct bolt in and its upgrade too, 6 speeds verses 5

a cr125 was a common swap back in the 3wheeler racing days
