  A dyno series consists of two or more dyno tests showing how incremental shim changes affect the damping curve.
  • For example, we will use the shock compression valving from a stock 2008 YZ 250.
    • (This will be Stack 2).
  shock comp shims
  10 - 40.2
   
  34.12
  29.12
   
  38.2
  36.2
  34.2
  32.2
  30.2
  28.2
  26.2
  24.2
  22.2
  21.2 b
   
  41 x 4.5 top out
   
  • For comparison, we will remove 2 shims from the high speed stack.  The dyno test will confirm exactly how this shim change effects the damping curve.
    • (This will be Stack 1)

  • If you have shim swapping experience, you might venture a guess as to how this shim change affects the damping curve.
  • Take a guess, then proceed to [dyno series tutorial pg 2] to see the actual change.
