Ill chime in here with my advice. I bought a 2007 black Speedmaster in May 2007 and it was my first bike and only been riding 1 year. With the great advice from the peoples here on this forum I have now put holes in my airbox, removed AI, changed jets in the carby, changed to allen head stainless screws on the carby and removed 3 baffles from each factory exhaust. I am not a mechanic and I have found if you give it a go you will learn so much more. The advice I have received from here has been spot on since I checked it with a dyno and did not need further adjustments.
I have had great service from Brent at Newspeedmaster.com and I am a few oceans away. Give it a go.
(Wife could not believe her eyes when she saw me with a drill with extension bits on it and drilling away at my bikes exhaust and it was only months old)
