Busa, take another look at the service bulletin.
Regional problem, probably not but Suzuki is laying blame on fuel additives. No mention about a tank coating gone screwy as heard from busa owners in other countries.
Blame is placed on the tightness of the screen material in the petcock and an insulator around the fuel pump motor.
Differant states have differant gasoline additives(regional), seems that Busa's from all differant states are afflicted and differant countries as well.
Suzuki is fixing the bikes that surface with this problem as a service bulletin and not as a recall(a recall would be for a larger group of bikes defined by a serial nmber range).
