Just curios if a newer or even older 125-250 RM motor will bolt into the same frame as a 1981 100 RM. My motor in my bike went after about 25 minutes of riding and i don't really wanna even rebuild the 100 if i can get a newer or even older 125-250 to fit in the frame with little or no mods. There seems to be a tight spot in my motor when the piston is about half way up the cylinder and there are quite a few metal particals in the crank case |
