I found that for approximately $20, an 02 Sensor By-Pass Plug is hard to beat. It richens up the bottom end just off idle and reduces drastic engine braking when you roll off the throttle in low gears. I've had one installed for over 2 years now, and it made a great improvement in drive-ability. You will need ONE Plug for each 02 Sensor your bike came with. See the link below...

I've had this installed for about a year now. I got curious about how much it was actually doing recently so I took it off for a commute to work and back just to see how noticeable the difference really is. It really does make a HUGE difference for the better. Without it installed it's impossible to keep the throttle steady under 3k RPM because it just generally had terrible fueling. It was actually kinda of infuriating riding in traffic, I have no idea how they shipped the bike with that terrible of fueling stock.
