Yea, ive been thinking more about it. It also looks like i would have to do some frame mods to get an XR engine to fit. My dad has one that he is going to bring over next week anyway to see if it will fit.
Ive been staring at its engine on the bench since i pulled it out, and im really thinking i will just fix it. It already has great compression, but theres alot of gunk in the bottom end. A gasket kit on ebay is cheap as are most other parts for it. The main thing that im missing is the carb and some cables.
Heres a pic as it sits all naked on the table.
