The gen 1 Vees tend to run lean at low RPM and above idle. Mine made me crazy because I couldn't cruise smoothly at 3000 to 3600 RPM on back roads. Getting the ECU flashed, as another Trooper suggested, is the remedy for that, or getting a PCFC installed and tuned to your bike. It can be smooth as a baby's bottom after that, if the mixture is just too lean.
If you are riding along at around 2,500 and give it some throttle, will it pick up smoothly? If so, it's likely mixture.
