I have a 1992 kx 250 that requires a new clutch basket as there is play between the roller bearing and the basket starter gear. Aftermarket baskets will interchange between '92 thru '05 but you need the starter gear (which is bad on mine) and the larger gear which engages the crank. The factory baskets thru these years all have the same first five part #'s but have different last four part #'s. So clearly the actual basket is the same based on the aftermarket baskets. My question is do the other years have different gears that would prohibit their use in my engine or are they actually the same baskets with different numbers (last four) because of the year??
