  Clutch Break-in
  For best performance and longevity of your Horstman or L/T oil clutch, proper break-in is crucial. After your clutch has been blueprinted, the springs have been pre-set so that the stall speed will be 8000-8500 RPMs.  
  Step 1: Properly install your clutch on the engine, and make sure the oil is at proper level
  Step 2: Run a normal 8 lap practice session
  Step 3: after you come in, adjust stall speed half way between recommended stall speed, remembering a 1/4 turn clockwise (Horstman), counterclockwise (L/T), is equal to 250 RPMs, and then repeat step 2.
  Step 4: Adjust to the recommended stall speed.
  Step 5: Change clutch oil and go racing!
