Welcome to the board. The only problems that I have had with my 2000 has been dealer induced.
Here are a few of the common concerns:
1) Clutch noise (common
)
2) False nertural between 5 and 6 (mostly caused by lazy shifts
)
3) Subframe on 1999 and 2000 ( there have been a few that broke just behind where the bolt to the main frame
)
4) Temp (watch your temp when stuck in traffic on hot days. The Busa likes to run hot when there is no air moving.
)
5) White stuff (sediment) in the radiator overflow bottle. (normal
)
6) Fast tire wear (normal )
7) Uncontrollable erge to ride (habitual
)
8) The grin and chills that you get when anybody mentions the word Busa. (Busaitus, no known cure at this time just keep riding as much as you can to prevent the depression from kicking in.
)
9) Being unable to accept that the Blue and Silver is the fastest color (denial
)
10) Being the criticized for buying a bike that weighs so much. (jealousy
)
11) Not being able to got to bed at night without one more trip to the garage to say goodnight(sickness
)
