Not much, truthfully, just dotting all i's and crossing all t's.
Full build will be:
Racetech springs + heavier fork oil in forks
YSS stage 2 rear shock
Easily removable number plate (eventually with LED blinker strips and a small removable LED headlight)
Shorter, thinner bars
Kenda Kwik KD-1 tires
Lever guards/moose hand guards, not sure which way I want to go here yet.. I would swap the hand guards over to the CBR when tracking that
Ram air

Thinking of possibly doing a clutch cover swap as well. There's an aftermarket clutch case cover that eliminates the oil flinger and lets you install a paper oil filter, it also has a glass viewport with a full oil indicator so no more dipstick. The biggest benefit to this would be eliminating the flinger though, that's like 5lbs of spinning mass gone.
If I do the clutch case I would also swap out the stock clutch springs for stiffer aftermarket springs. I may do this anyway though, I just need to feel how well it grabs while racing.
