XR motor question

[shudup]

Just a quick question...... What years XR200 motors and/or cams can be used in '85 200X.

I did a search but was un sure on the exact years.
thanks

1984 was the change over from 2 valve head to 4 valve head in the XR200/XR200R's. Anything 2 valve will fit. The cam you want (the best one) is out of a 1980/81 model. The ones after this are different (when i say different i mean the lobes are different shape but still work and bolt in. Just not as fast)

When you buy them new they sell you the later model ones no matter what 2 valve year you tell them.
