What lines is the fuel coming out ? Most likely your float level is off.

Pull the carb off (two clamps) pull off the bowl bottom (four screws) check the floats and see if the needle valve is stuck.

its one of a few things

1. your fuel valve seal is worn out and its leaking from there and dripping down the side of your carb(probably not but worth checking)

2. your float isnt set correctly and is set to high, letting to much gas into the carb and is coming out the overflow tube(most likely)...some one on here probably has the specs to set it at, hopefully they will respond and be able to tell you soon or you could probably find it on the net

The factory spec on the '03 Mikuni is 15 mm.
Instructions for setting it are here:

possible cause #3: your "Needle and Seat" are worn out
