Anyone know will a Cylinder off of a 1984 CR 125 fit a 1985 CR 125. The motor thats in my bike is shot (Someone welded the hell out of the side crank case right behind the clutch)so i bought a full bottom end off ebay out of a 1985 and all it needs is a Cylinder head and clutch and side cover. I was going to use all these parts off of my old motor. The ebay listing said it would fit 84-86. Is this correct?
