Aim VPC

Gipper if that's all you plan to do with the motor you can leave your spring and go with the VP84LT. It'll drop the clutch pull 20% and add 20% more grip. I found that one on Amazon from Powersports Superstore for $246.
I just decided to do the VP95 on put the stock Spring back in. This way I know I'm covered if I ever decide to do more motor work.

In this pic you can see the ring scar from the stock collar on the Spring.
In this pic you can still see the scar and that the vp84 is a smaller diameter.

Gipper, installing a VPC on top of your Barnett will NOT bring your clutch pull pressure down. But running a VPC on top of a stock spring should bring your high RPM clutch spring rate closer to your Barnett springs. I run a Screaming Eagle VPC on top of my stock clutch spring. The VPC has little spring loaded weights on it. When RPM's are at idle, the springs keep the little weights in, and you just have stock clutch spring pressure and pull. But as your RPM's increase, the weights kick out, increasing the spring pressure. Then when your RPM's come down, the springs pull the weights back in. Your clutch spring pressure and pull stays the same at idle, but then increases with RPM. So you get the easy pull of a stock spring at low RPM's, with the performance of a heavy spring at higher RPM's.

The convincing part for me to do the VP95LT that was pointed out by skratch is that it'll hold up to 148tq with the stock Spring. Doesn't bother me a bit to take that stiff SE spring out. It's done enough damage.

The Barnett spring was allegedly going to increase my clutch pull tension by 35%-40% if I remember correctly (felt more like 80%!), so I just need to think it over to determine if a 20% reduction will actually reduce the wear of clutch cable and lever components by more than that. If I left things the way they are, I'd surely be replacing pins in the clutch level in a matter of months, and be replacing the clutch cable all over again in a year.....no thanks to that!
