also depends alot on your riding style,if your spending alot of time over 4,000rpm think a clutch spring is mandatory even with a stock motor.

I have an S&S 107 in my 1990 Evo. The clutch is original and stock, with just a Barnet clutch spring. Motor gives just over 100 HP/TQ at the rear wheel. Your TC should manage significantly more performance than mine with no more than a stronger spring.

Not a whole lot over stock HP, if you ride aggressively or carry a lot of weight.

The clutch springs had become progressively lighter from 04 and up. 06 and up are real light. Gave the consumer easier pull.

You can go quite a ways with the SE spring. That sucka is potent.
Hard on the wrist though, in heavy stop & go traffic.

I'm going with a VPC clutch now - no sense waiting to start degrading the rest of the clutch.

I had one on my last bike and loved it.

I run the VPC 83T (they now sell them as 84T) along with the 98A clutch spring (lighter than the SE) on a stock clutch. Bites hard at the rev limit, with a nice easy lever pull. I love this set up!
