I was really getting tired of getting water in my carby and the filter getting choaked in mud so I had a crack at making my own air box and though I'd share it with everyone, its pretty rough but it does the job and won't cost you a fortune.
To start off I found some down pipe which I think is about 80mm in diameter and cut it the same length as the foam air filter. Then I drilled many holes in it like below with a 10mm splade bit. This will slide over my filter. (note some pics were taken before the holes were drilled.
The screws will be explained in a moment. I then found a larger piece of down pipe about 100mm in diameter to slide over the smaller one and cut it about 40mm longer then the last.
The screws simply hold it central inside the larger pipe.
A end cap was then put over the end of the 100mm pipe.
The inside piece will slide in with about 20mms of space between it and the end cap of the white pipe to allow maximum air flow through the filter. It was then painted and fixed behind the rear shock using these things.
they were screwed into the pipe and then clipped onto the subframe. The hard part was finding some tube to connect it to the carby, I managed to find one which is fuel resistant and could bend just enough with out kinking. Hose clamps were used at each end of the tube to hold it in place but they are not in the pictures.
And to top it off it is hard to see it underneath and it actually works.
