How do I make my 600 fazer faster?????

fit a turbo....

Seriously though, without spending big money and then having to spend more upgrading suspension etc then it's really not worth it. Small gains can be had, as mentioned already, by k&n air filter and a decent exhaust but the bhp gain is tiny, a few bhp at best. After said mods my bike definately rides smoother and seems to pick up speed better but that may all be in my head and because it sounds nicer then it feels faster...

Spend your money on a few track days/tuition or on a bigger/faster bike.

I would only say that it would be worth it if you're really in to tuning and have mega bucks to throw at it! This tuning game is all very addictive. Once you change the cams, you'll find out, well this mod would make that one work better, and then, well, I need to do this mod to make that right, and then....! But if it's your only bike, then getting a faster bike in the first place is the best way to go. I agree with all the comments that the manufacturers spend a lot of money getting their bikes right, and few if anyone else can do as good a job as they do.
If sheer speed is your thing, get into drag racing. £££££££££££££!!
