1985 Xr200r Motor

[2hundredx]

I know these motors have the different heads but can u put an 85 200x top end on one? thanks

[4 wheels?]

If you mean the whole top end the engine will cool better because the 200xhas bigger fins.

It's my impression that the 4 valve motor is more akin to the 350x motor than the 200x, so I doubt it, but I may be wrong. :confused:
