Secondary ?

[CROW]

Can someone please clear something up for me?

Everything else staying the same, what effect will a larger initial force/rate on the secondary spring have on clutching? (more or less backshift, more or less upshift) Same question, but for the final force/rate?

more initial force= "zippier", slower upshift/more RPM.
more end force= more RPM/quicker backshift.
The helix angle does most of the work, especially at mid-top, the spring has more noticable impact at lower speeds.....if that makes sense

This would also give him higher clutch temps wouldn't it? From the spring fighting the helix?

From my understanding, in theory you want to run as much helix as you can, and least amount of spring.

Maybe i'm wrong though, been awhile since i've done much clutching, and I'm new to the Team rollers.

Time to review my Aaen clutch tuning book haha
