Clutch Spring Question.. Need Help

[jmbones]

I have a 99 Yamaha Vmax 500SX

It pulls out around 4300 RPM. I do not think this is stock and I want it to pull out more around 2000-2500 RPM. What type of spring or setup do I need?

Thanks!

Something with a lighter preload will accomplish what you are looking for.........But you want to engage around 3500-4000 or so. Otherwise the motor makes no power and you will see poor performance on take off.

Thanks. So do I just need a new spring or are there other parts involved? Basically I want it to pull out and perform how it did stock. It seems to be a dog on bottom end.
