Need a 1988 KX 500 crankshaft

<< < (2/2)

umberto:
Dave916 knows a lot about the 86-88 500s. I asked him so many questions when I was building mine. The 88 motor actually shares a lot with the 89 and up motors, with the cylinder (KIPS) being the major difference.  The cases are pretty similar too. I actually bought a set of 89 and up for mine to keep as a spare set (thanks to Sandblaster). The 86-87 motors have a lot of similarities, but not much carries forward to the newer models besides the cylinders, which can be made to fit.

 Yes i am 100% sure any  88/2004 crank will   fit / {Circlip primary gear }
88 looks a little differant because of balance holes on ether side rod conrod /89on crank is just countersunk more in that area {they are the same weight}

Probably 70% of all secondhand kx cranks  will have a worn journal/  look for shiny journal

Thanks! Found a new 89-04 crank assembly for about 500 so I think I'm gonna try to go with that.
