You KDX250 motor was based on the '88 KX250. I don't think a '92-02 KX250 crank is going to work.

Can your original crank be re-built?

$150 is not a bad price. The parts are around $100 and labor for $50. Someone has to pay for the 30 ton press and truing jig, dial gauges, stands, etc. Most folks don't usually have such tools laying around, but if you do, then congratulations and good luck. :-)

Do you have all the tools?? Do you have the service manuals?? How do you plan to rebuild a crankshaft otherwise? It is a high precision job which requires a high level of skill and craftsmanship.

I think that rebuilding a crankshaft is the most difficult maintenance task possible on a KDX. I suggest you leave it to an expert. Otherwsie, do you do combined shipping on your e - Bay (parting out a KDX250) auctions?

dude would your really install a used crank in a motor? That is just asking for trouble.

Just think of all the work it takes to get there. You want to do that again anytime soon? Rebuild the crank or if you get a used one, rebuild it before installing. Common sense
