My brothers got a 04 same generation, its a sweet bike ride and handles great and's definately got some balls, compared to the busa motor wise its alot smoother feeling. He's had alot of electrical issues with his over the years, random wires shorting out, stators, starters, random wires disconnecting, i wouldnt blame the bike totally but some of it just seems to be oddly designed in the electrical end.
He's got 6" extensions on his and lowered 1" in the back, micron pipe, k+n, pc3 and a ignition setup. Its no busa but i would take one for the right price
