Thanks guys.
Oldyzman, unfortunately it’s just a motor, no indication of where the rest may have gone. My mate has found it and is bringing it home from his hols.
The motor in question will be for sale. It is not in a frame so can’t be run. It turns over freely and has compression. Gear lever and kick start are attached. I‘ll double check but I think it has the carb and ignition.
The big question, A 74 KX250 motor, what’s it worth?
