i was wondering what sort of performance upgrades i can do to more f4i to get more out of it besides sprocket, slip on ,pc3, and filter?

 

well hummmm how much money you have ?
you could do
Engine Internals. [ Pistons / Cam shafts / Head porting ] not something everyone can do , i know i cant avg cost your looking at 500- 5000 dollars
you could slap a turbo on it :P 3500 + bucks
Nitrous ?

those are the other performance mods i can think of atm

 

Red "RR" stickers

 

No you got it all wrong...you need "1000" stickers on it instead of 600. lol

 

o hell yea and maybe some flames and a blue neon right

 

Seriously, the F4i is still a very fast bike. Engineers spent alot of time and work designing your bike for the best performance. If you really want more speed than 150+ mph. Save your money and invest into a 1000RR or even a Hayabusa 1300. But I personally don't go over 100 very often, its fun but I know I can do it. Most of my fun is zipping around town.

 

pink its pink neons that make u go faster or was it purple wait a minute its pink an purple thats it LOL

 

im not concerned with oing overly fast i just want more bottom end

 

Oh, thats easy, change out your sprockets and chain. stock is 16/46 teeth. Take it to a 15/46 and you will see your low end increase.

 

well you could do some mods to the engine thats going to give ya some more power . but can shorten your engine life :P

you could always get some new rims its like putting your bike on a diet, you get some more speed by dropping weight
