Ramp profile
"Controls the size/magnitude of the shift force" 

Lower angle will provide more shift force.
Thinner ramp allows the tra lever center of gravity to be farther away from the clutch shaft centerline - Provide more shift force.

Higher angle will provide less shift force.
Thicker ramp allows the tra lever center of gravity to be closer to the clutch shaft centerline - Provide less shift force.

Clickers
"Changes TRA ramp angle"   Ramp profile controls the size/magnitude of the shift force.
Determines how quickly the engine will rev/accelerate.
Clicker 6 raises ramp angle to highest point - Quickest engine response
clicker 1 lowers ramp angle to lowerst point - Slowest engine response

Learn what your clickers do for 1)rpms and 2) how the clutch shifts.  Cycle them down to 1 and go to 6 and figure out which one allows the cltuch to push the hardest, you feel the best acceleration however have good rpm response when you chop the throttle on off or when the snow load changes.

These particular ramps below, I ground all the ramps to have the same curve as the 441 in the later part of the ramp(s).
What I wanted to do here is have all the ramps maintain their individual start profiles for the first 2/5th of the shift.  Then have the last 3/5th of the ramp have the same (441)"push force" to full shift.
