Clutch

[Bubsbuggie]

Trying to solve my clutch problem. I have a g16 yamaha cart with a 23 HP B&S Vtwin. Cheta cam, rev kit, key advance, stock carb (for now). Clutch is a Cvtech 06 serie. Clutch engagement rage is 1800 rpm -3600 RPM. I consider the working range on my vtwin to be 1200-5000RPMs.

Correct me if I am wrong!!
I need a clutch that engages at 1200 RPMs at tops out at around 4500RPMs.

With My current set up it acts like an 1800 stall converter. I have to press the gas and rev the cart up to 1800rps from 1200rpms before the cart starts to move. Could you imagine how many care accidents would occur if our automobile worked this way. My cart should begin to move the second I let off the brake pedal or very close to this point. What can I do to make this happen?

CVT manufacture says I need a spring with 400/900 newton (Measurement) but CVT doesn't make one. Anyone have any ideas? How different are they from a stock secondary clutch system spring?

I am also open to other better clutch systems. I have the room to go bigger to maybe 9" diameter if need be but don't want to go smaller??
