Klx 250 engine need advice please

Hi people I have a klx 250 1994 which I have sized the crank on. I have found a kx 250 bottom end from a 1991. Anyone know if this would mount with my top end?

Welcome to KF.

I am not sure on the engine specs much. Have you checked out your favorite fiche to see if the crank numbers are the same? Good luck on the search.

I think its waste of time doing this and i m not sure if it is worth it.

Better see if the kx's conrod is the same (length, pin dia, Big end dia) and thicker than klx's OEM rod. If you modify the top end seriusly, you will need stronger rods.
