Yes, Save money on the bike; spend on mods.
Brocks Full system exhaust new Alien head or CT shortmeg. ECU flash or Bzazzaz fuel module and Speedohealer. Get BST CF wheels if you can afford. Carrazzeria wheels are nice too but not even close to the weight reduction. Shorai lithium iron battery. Pazzo levers, get some reasets, I like Vortex but I have Satos which are also very nice (just a bit small lookin on a busa). Quickshifter is mighty cool. I have an HM, I'd go with the Bazzaz fuel module that has QS and TC.
so there. you're in another 6K$ good luck shopping, brother.
