Jamie recommended the spring they install on the new 103's. I don't know the spring pressure and I haven't had a chance to ride since installing it. I'm hoping that it will be strong enough. How does a person find the pressure rating on the springs? The parts guy wasn't much help.

I had to switch to the 98A spring because of some slippage issues. Works great! I'm running the FM 107' kit with no headwork.

I do not know for a fact but I have been told 280. I took that one out of my 08 as well. It feels super light to me, lighter than the 280 number that I was told.

I spoke too soon. I failed to notice that two of the steel discs have grooves in them. Fortunately I caught this. I think these discs were in the back of the clutch pack so this must have been where the slippage was taking place. After weighing a few options I am ordering the Energy One clutch pack with extra disc and performance spring. P/N BT-14. There are some good deals out there to be found. $127.95 plus shipping. Not bad.
