Principles
A fundamental truth as of law.
A given result by it's mechanical contrivance.
Modus operandi that which apply or modifies a mechanical power to produce a certain result.


Flyweight
"Determines rpms" (Example rated rpms 8000)
IF; THEN, Result[s]
  • Need less rpms; Increase flyweight mass - The TRA lever pushes harder.
Example, IF you reveal 8400 rpms with 40grams flyweight, THEN increase flyweight to 42 grams.
  • Need more rpms; Reduce flyweight mass - The TRA lever pushes less hard.

Example, IF you reveal 7700 rpms with 43grams flyweight, THEN reduce flyweight to 39 grams.

Ramp profile
"Controls the size/magnitude of the shift force"  (Illustration)
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

Temperature
Regardless of temperature you measure, whether its hot or cold or warm or burning or freezing - The lowest temperature you'll measure is when having clutch calibration allow the engine to run at "rated rpms" on a sustained wide open throttle pull.

Engagement rpms
(Primary spring) IF you want to raise engagement rpms, THEN increase the primary spring start force.
(Ramp) Increase ramp angle under roller at the start of the ramp.
Example; IFusing a 414 or 415 or 413, THEN change to a notched 419.

Rpms near full shift
(Primary & secondary spring) IF rpms are low or diminish as shift increase, THEN increase final force of the primary or secondary spring.
Example, IF rpms are 250 low while using a (XXX / 300), THEN change the spring to a (XXX / 320).

Rpms near full shift
(Helix final angle) IF rpms are low or diminish as shift increase, THEN reduce the helix angle "at that point" on the helix.
Example, IF rpms start to reduce from rated while using a (XX / 56) degree angle, THEN reduce that angle to a lower one, like a (XX / 52).

Upshift rpms
(Primary & secondary spring) IF rpms are low as sled speed increases, THEN increase start force of the primary or secondary spring.
Example, IF upshift rpms are 400 low and slowly increase to rated rpms when using a (130 / XXX), THEN increase the start force to (160 / XXX).

Upshift rpms
(Helix start angle) IF rpms are low as sled speed increases, THEN reduce the helix start angle.
Example, IF upshift rpms are 200 low with a (44 / XX) start angle, THEN reduce the start angle to 40 degrees (40 / XX)
