the flyweights are further out then, so they have more force to push the clutch shoe against the clutch bell.
Interesting hypothesis...
So to keep it simple, V = 4 and r = 2
a = 16 / 2
Then if we maintain same velocity... V = 4 and increase radius to 3
a = 16 / 3
Where Mass x Acceleration = force, the acceleration decreased as the radius grew.
Thanks for the food for thought, but I am confused by this hypothesis... the mass of the throws do not change either and assuming the ramp is the same.

What is good about this finding is that the velocity must increase as the gap is larger, hence the engine is revving higher in order to compress the spring. The spring is a linear force which means the shoe actually slows down but the acceleration of the free engine increases the velocity of the throws to overcome it. So engine tune, pipe, manifold and power band have a great deal to do with the setup of a clutch. And they say I think too much, in fact I'm ignorant and thanks again for the food for thought!
PLEASE correct if I am wrong.
