I have some questions about the conversion??? I like the idea of the XR 200 motor in a CR 80 or 85 frame. My question is can you take a stock CR frame and put a XR motor in it with just customization of the motor mounts? Or do you have to do alot of cutting and customizing to the frame itself. I see BBR and other companys have frames for this....I'm just trying to see if i can do it myself.
