Adam - you have to take what Buell says with quite a bit of salt. After all, its the same company who cubed the bike. They also had beginners in mind, not performance. Their is a difference. Its nice and tame for the most part at stock (keep the rpms down, shift early), and they went to great lengths at keeping people thinking it was a beginners motorcycle and you wouldn't hurt yourself with it. Keep it slow and farty doesn't mean you cant open it up a bit and see for yourself. I sweat they deliberately suffocated the bike to keep it down. All you have to do is let it breathe a bit and suddenly its a different bike.
Looked at the chart again - thats the worst shifting advice I have heard to date. 5th at 45 - 50? 3500 you are just starting to hit the power band, no pull below. Ha ha - anyone else out there that reads that chart, please, dont shift like that, your bike will hate you.
