New clutch if you can swing it.
Amen!Everything I have ever read says get the new primary. It will really awaken the 1000. I'm like you, I'm not a pin it and grin it kind of guy, but I do like to feel the power especially in short bursts...With practice I think you would be able to control it even with the new primary....My advice would be to call VFJ and tell him your concerns. He will steer you the right way...Good luck with your choice.
I just purchased a CV Tech primary/STM secondary for my 1000. Ready to get em on.
Bought em from Jace Cheramie racing in Houma LA
