i have the chance to get a 2002 kx 250 that needs work.... it needs a new kicker shaft. from what i understand from the guy who owns it is he replaced the complete top end and ran 3 or 4 tank of gas through it... then one day it got flooded and when he went to kick it the shaft broke. he said the bottom end is a 2003 out of a bike that had a broken frame.... also the front suspension is from a new kx450f i think.... anyhow my question is this how many years they made the kx 250 compatible with the 2002... from what ive been reading the 2001 and 2003 are basically the same....i know nothing about the newer kx. the newest one i owned was back in 1992. i dont want to buy a pig in a poke kinda deal that im gonna have to mix and match parts . if its just a matter of a few bikes are the same then i would feel better about getting it.
