I'm running a 750 but the principle is the same, just pull some controls off of a newer bike. You can pick them up on e-bay all day long for 15 bucks or less. Wiring is easy, just takes a little sorting out. I swapped over to 2006 GSXR 600 controls. Best $35 I've spent on my bike to date. Plus they came with new master cylinder, clutch, gel grips, levers and some clip-ons. I'll sell the clip-ons and make a few bucks back.
The only trick to wiring the controls is to group items. If you know what the honda side does, just look inside where the wires come out on the controls. After a few plug ins you'll get it right. I stared at it for a few days thinking I'd never get it done. One day I sat down with a few beers and I had it rewired within 30 minutes.
