Same answer I gave you on eBay
FITS 87-93 KX250 - 13161-1145
Somebody might know this...
In 1994 the kx500 switched from a smaller spline size to a larger spline size on the shift shaft.
The rest of the shaft is exactly the same.
So, you can drop in a 94-04 kx500 shift shaft into a 89-93 kx500 engine and run the 06-06 kx450f shift lever...
I'm wondering if the same sort of thing is possible for your 92 kx250.... IE try a 94-96 kx250 shift shaft but be prepared to buy a new shift lever..
Anybody?
