Not a lot, it already has the shotgun exhaust and appropriate chip, I added an Evolizione Cycles Adjustable Fuel Pressure regulator, Brembo Sintered HH pads, a Michelin PP rear, I changed the Slave cylinder seal and flushed out the lines, bled the rear brake, changed the levers to stockers, the shifter and brake pedals to stock. I had to rezero the Tach, I straightened and welded the sliders. I changed the cover on the left side to an undamaged one, I straightened the fairing, I have a new lower triple clamp. I installed TLR rear signal lights, replaced the front signal lights, I plan to install an integrator.
Not much really, only had it a month or two. Did I mention the kill switch and grips I replaces, I also adjusted the TPS, and rerouted the hoses to stock and such.
