Yes. MY '92 KLX 250 had the KX250 clutch plates fitted - common mod to double the clutch life. As the plates wore they went back to normal spec (for the KLX) and started to judder, so I bough the missing actuator spacer (a washer) and judder spring and it was fine again.
i posted this to gain some info as i installed a aftermarket clutch kit and wasnt sure if i needed the judder springs, on a stock clutch the bottom friction plate is smaller so the judder springs sit inside, this makes the gear changes smoother blah blah blah,,
i was under the impression with aftermarket kits u removed these springs, turns out yes u can if the kit consists of all equall sized and shapped plates,
BUT after stripping the clutch tonight i found out in fact i had a smaller friction plate in the middle of all the other plates (completly out of its place, and this caused wat i was going to be getting at witch was a very loud and not smoooth gear changing or pulling away clutch)
i refitted the judder springs and the small plate to where they are supposed to go and now its fine and quite (for a ktm anyway)
not sure it was needed to explain all this, but its usefull information that might come in handy one day :D
Mine was like a metal washer/plate thing that went around the outter edge of one smaller clutch plate. This plate was bent slightly outwards on the inner face so acted as a perriferal spring to hold tension in the clutch plates and some how stops the clutch pack from grabbing as you release the clutch.
they fit snug on the outside of the inner hub, my ones are like a flat thin hoop ring sort of thing, somethin like pat butcher would wear on her ears, the other was a little thicker same size around but it was as if someone had punched up thru the middle edge and bent it all upwards,like a gym hoola hoop but cut in half on the edge, and then cut in half again...
best way to describe mine lol
