Just a quick question to see if anyone knows. I have a 1987 kx 250, and I would like to switch out the crank. Previous owner let the piston skirt smack the top of it and put a mark in the cam on it. Probably would still work but since I am going to change the bearings and seals I thought I might as well put a different crank in. I have looked at fiches but am not sure of the compatability. Does anyone know if there are any year cranks that will fit the 1987 motor? I know the 1986 won't fit because the crank shafts that go to the main drive gear and stator are different od than the 1987 but was wondering if the newer ones will fit since the bearings do fit from 1987 to 2001. Any help or advise on this would be great. Thanks in advance!
