There are a number of things that can affect your slider's reaction.
  • Incorrect air gap
  • too heavy an Oil
  • incorrect basket endplay
  • too large of an RPM gap between the 2-step box and the actual stall speed of the clutch
  • condition of the outer basket
    • If it has been a few seasons since you've had your outer basket serviced then it might be time to have it rebuilt
    • A basket with weakened springs can cause an erratic operation of the clutch as well
