Did a little research,Doug. I may be starting to see the problem. Are the clutch springs in place and tight? If so,and the hub still spins,check them for free length. The manual should quote a spec. The (80's,anyway) KDX clutches are a little odd,what with the pressure plate inside the friction discs. Are 97's the same? If the springs have tension,and the clutch still isn't locking up,Congratulations on your top-notch toasting job, Gooby's air impact might be your only alternative.
