why would you want to?? you can get just as much out of carbs, although you cant plug you computer into carbs and change the settings :bounce
+1 I have the same bike and I wouldn't have it any other way. I love the way the power "hits" with carbs, FI is too smooth. But anyway, it'd prob be easier to do a motor/tank swap than it would to convert the 97 motor to FI

Hey buddy I bought a 99 GSXR 600 and someone went Edward scissorhands on the wiring harness so I bought a new wiring harness well it was used but the new harness was off of 97 which I was under the assumption they are compatible everything plugs in but the two plugs that plug into the two little cylinder shaped canisters underneath the four carbs I don't know what you would call those are not on the harness I'm confused if somebody could help me out I'd appreciate it

Firstly, it is basically impossible or at least so much work that I can't personally imagine it (crank and cam position sensors, modifying the rotor, modifying the electrical system :eek: )

Secondly, a properly set up carb engine will run better as a performance machine than a fuel injected one, in almost every way.

Fuel injection came about to meet emissions requirements and put a catalytic converter in road vehicles.

Ironic that people go cutting out their cats for performance but others want to add all that shit!

Fuel injection on bikes is 'dumb', there is no active feedback so you get no 'adaption' to the running state of the engine (changes in intake volumes with engine wear, temperatures etc). In a car you do, there are lambda sensors (OK, there are on the very latest bike for Euro 5, not on older GSXR) there are MAF sensors and manifold vacuum sensors. None of that on bikes, it is a fixed map and your engine probably ends up running richer and richer over its life as the engine wears. Not sure. Something like that.
