Busa low idle on start up?

[Belzybob]

Dose anyone know what is happening here or has it happened to anyone else?
The bike has only done 2,200 km and the only thing done to it is the computer flashed and Yoshi pipes .

Any information is appreciated.
Cheers.

Yoshi mufflers or full system? Was this a Yoshi 'tune' map mod or a full mapping done on a dyno? Mine is at 4500kms now and I have R77 mufflers and a Yoshi mapping tweak, but none of the symptoms you describe.
