Dual Port Injector Bodies are good for about 10-15 hp with the correct tuning. See them here

Get the Box-r ram air kit, full graves ti, graves velocity stacks,powercommander IIIR, and graves slide stops. you should see 150+ horsepower with these modes, granted by this time you would have spent $2500.00 dollars. The result I got was great. I can murder stock gixxer 1000s, on roll-on I am there with gixxers that have work also, at that point you kick ass on rider ability.

 

I'd go w/ dropping 1 tooth in front. That seems to me to be the best bang for the buck.

drop a tooth in the front sprocket and lighten up the rear sprocket get a new d.i.d chain won't add much more h.p but man will u notice a different in acceleration :rock

Very good, It won't add any but it will free up or find lost HP. Get a good 520 kit and stacks for the most noticable difference witht he least amount of money.

 

A quality full system(Graves, ARATA, Akra, Arrow, Ti-force. and completely remove the AIS, a PC3. Trim some weight off of it or you.
