Hi, the backplate is bent up top and bottom to the angle needed to meet the alloy cover, then I welded another strip alongside to forma channel into which the cover fits, then the two end plates push on, eventually two lengths of threaded rod will be used to hold the lot together.

Mine fits under the bonnet and it's made from carbon fibre

DIY styleeeeeee



Cut down the standard ST1100 airbox, cut one end off it, glued on a plate onto the cut end, then made up a carbon fibre plenum thingy that goes between the ST airbox and the ali tube connecting to the filter. Carved the plenum out of polystyrene, sanded it smooth, slathered it in epoxied carbon, carved out 99% of the polystyrene then disolved the rest out with petrol. Walloped a plate on the end to bolt onto the airbox plate and happy days all round....

and yes I know my garage is (was) very messy....

Here's mine - more a filter box than an airbox, on CBR600 carbs.

Hi David that one is very smart, how does it fit to the carbs Cheers BILL

Bill,

I was fortunate in that I got the original bike airbox with my carbs - this had the mounting rubbers that go between the carb mouths and the filter back-plate. Having the right kit always makes life much easier!

If you go to my website (www link below) and open the 'bike carbs' link, then the 'Fitting to the engine' link, you'll see some details half-way down the page.

A way I found of gaining space was to use the flat underside of my bonnet bulge as the top of the airbox .

I know their not bike carbs , but they are at least bike throttle bodies

Mines homemade for R1 Carbs.
I used the bike airbox, cut the mounting clamp area out, and sealed it into an aluminium box.

The carbon airfilter is from Car Builders Solution.

Had it on the rolling road, and only had to increase the main jets. No Dyno jet kit required. Very Happy Rescued attachment Airbox1.JPG
