I have the 2004 TBA, and I have this problem since day 1, it does get quieter though as the engine warms. When I first start the bike, I usually let it tick over so I can take the choke off completely before I ride it. Every now and then it feels like the whole bike wants to jump forward. Also I had a little trouble when I stopped at traffic lights and had hit neutral, it was a bu**er to find first gear, I must admit now I find it a lot easier. Just over 2000 miles on the clock.
