Like the title says the bike hesitates it idles fine and after 2500rpms it moves on out.. It has a full muzzy exhaust and a pcIIIusb it did it before the pcIII and after i installed it. I got my map from powercommander.com. Any suggestions is the normal or

? other than that it runs perfect no backfire its an 07 with 3700 miles thanks
 
Did you run the exhaust without the PC? Have you done the airbox mod?
 
No i bought the bike with the exhaust already on and i puchased the powercommander and installed it myself. No air box mod yet though
 
Two people this weekend have told me that ethanol makes their Busa react exactly like your are describing. I haven't noticed it with mine.
