These worked fine, I just crushed them a little in a vice to make them wider so they didn't slop around so much. The hole in the airbox is quite big, more like 7.5mm

Cheers

Someone want to explain this? I didn't see anything about what nuts are being replaced or why.

The wellnuts in question are those pesky rubber things used to hold the injector covers onto your airbox. They are also used around the screen to hold that to the top fairing or cupola or whatever you want to call it. The trouble with the wellnuts is they can work loose and the threaded insert (on the inside of your airbox) can drop down the throttle body into the combustion chamber of one of the cylinders. If you can imagine the effect of dropping a ball bearing in through the spark plug hole of one of your bikes cylinders then replacing the spark plug and starting the motor, that might give you an idea what a wellnut insert could do.

Just found this thread and it hits home as I took those little covers off for the first time to trim my TB air bleeds and already two of the rubber wellnuts were ripped and about to fall off. I followed the advice of Donsy and Noel and got meself some rivnuts and squeezed them into place. I borrowed a tool from work (lot's of mechanics at my work ) but it only utilized standard sizes (not metric), so I chose a slightly bigger size than the M4 that came with the bike as to be able to use the tool. The rivnut size I used was #10 24x0.475 and the screw was a #10x24x0.625 (or possibly 0.75 :/). And is that really English/Standard or some other weird convention? #10? Anyway the rivnut fits nice and snug into the airbox holes BUT, because the rivnuts squeeze up to the airbox holes properly (unlike the rubber wellnuts that can bend inside the hole), I had to oval out the holes in the plastic covers a bit to be able to align the screws into the rivnuts, not a big deal though. Basically, I got free shite from work and made it fit. Oh and to clarify, I did not use the rivnuts that came with the kit as they did not have a lip to seat in the airbox holes. The rivnuts pictured I sourced from our hardware bins. Here is a photo log of my installation:
