My father inlaw brought back a bike from his farm shed for me the other day which seems to be a rm125 1975 model with frame number rm125 20334.the sad part is the frame has been cut at the bottom nder the engine area then welded in engine mounts to hold a cb100 motor and its completely covered in dust from sitting so long seat is stuffed handle bars guards tank are missing (thought i think i may be able to get the tank back). My question is is it worth doing anything with it ,are parts hard to find or should it just be scrapped (wrecked)
