My zx9r airbox doesnt whine, it growls, if that is a fault I dont want it fixed.

The noise remains.
So, output shaft it is.
Ill tackle this in winter. Time to enjoy the bike. Shes never had so much TLC.https://uploads.tapatalk-cdn.com/201...46516b20a4.jpg

How much would you be prepared to bet me that the replacing the output shaft bearing won't fix it either?

I'll be travelling past in the next 3 or 4 weeks and would be keen to have a look before you take it to pieces. the problem certainly sounds like its giving everyone a run for their money... Regarding the output bearing i'm with bob ( a bearing thats so noisey surely would have completely failed long ago) but i've got a pocket sized bearing/machinery vibration recorder and will put my own zx9 up on blocks and get the readings at 80 kph then compare them to your bike ... we could then place bets (or not !) with bob... pm me if you are keen.

Bearings don't whine, the growl & get progressively worse quickly until they self destruct.
Leaving it until winter would help prove its not the bearing, as it would have totally self destructed by then under normal circumstances.
