I changed to Hindle 4-1 system and mounted a Dynojet kit end of 1998.

- The airfilter case was drilled and a K&N filter was fitted.
- The Main jets are #140
- The mixture (pilot) screws turned clockwise until they seat then out 4 turns.

   According to the Dynojet chassis dynamometer test I have:

     Max Horsepower: 114 HP (on back wheel) at 10.000 RPM.
     (approx. 130 normal HP)
     Max Torque:     92.5  (N-m) at 7400 RPM

     See charts below for different systems.
