I know the stock plates and spring now slip at high rpms with just 75hp 94lbs/tq with the D&D baorzilla, SE heavy breather, and SEPST.....

If your going to do the VPC, it's only around $30 for the SE spring.

The 340 with the VPC pulls a tiny little bit stiffer than stock but holds most 103-107 motors that have a sound clutch to begin with. I also ordered the billet pressure plate and when you do that they throw the spring in for free, P.S , I also talked them into shipping it for free to boot. The VPC92 lessens the clutch pull 8% according to AIM.

Don't overthink the clutch needs. Go withthe recommendations on the Aim website and you will be fine. My "little " build is at 98/108. Has the stock HD spring and discs with an Aim 84T. Holds fine, pull is like butter.

Do you have to pull the whole primary cover or can it be installed through the domed derby?

You gotta pull it but if you just ease it off and don't yank it fast(I know I know) you can re use the gasket(new one is like 35.00) I re-used mine and its still bone dry 18 months later.

I'm interested if still available? Sent you a PM...
