What kind of engine does an 84 XR200R have?
A friend put an 84 XR250 dual carb engine in an 87 XR250 frame; it was a bolt in and the 84 dual carb air boot bolted to the 87 single carb air box. I owned that bike for ten years and never had a overheat problem and really liked the crisp throttle response of the dual carbs.
Is the 84 XR200 air box the same as the 85?
The 84-85 XR200/250 air box is the same as the 86+ XR200, just the carb boot is different. However the engine bays are different between the 84-85 XR200/250 chassis and the two valve 200 chassis. A friend put an 84 XR250 dual carb engine in an 87 XR250 frame; it was a bolt in and the 84 dual carb air boot bolted to the 87 single carb air box.
What should I do if my carburetor is not working?
For carburetors that suddenly show signs of being in a rich condition, gently whacking the bottom of the carbs to make sure the floats (tiny little pieces that control gas flow like the rubber piece in the back of your toilet) are free. Also check that the choke cable works.
