I did my own airbox removal and found it fairly simple. Also, you'd have to look at the side panels very closely indeed to tell it had been done.
see image 1 - carb mounts made from old s/s cafetiere - holes drilled to 8mm (top) & 9mm (bottom - later enlarged to fit round the upper carb connecting rod), 105mm centre to centre, and K&N filters (part nos: RC2890 & RC 2900)
see image 2 - carb mounts fitted
see image 3 - cutting down stock airbox
see image 4 - LH K&N filter fitted (note: lower mount for stock filter has been removed to allow more storage space for tools, etc.)
see image 5 - RH K&N filter, airbox cover, rear brake reservoir and fuse box fitted (the plastic screw holding the fuse box to the reservoir mount has been replaced with a s/s Allan bolt)
I had to remove the upper connecting rod and shorten the thicker/outer part of it at both ends with a file (by the thickness of the two pieces of S/S) it so that it would fit through the holes in the S/S(which I drilled out to the same diameter as the locating holes in the carbs) and back into the holes in the carbs.
I fitted the Wiseco 904 BB kit (AI removed and 18 tooth sprocket added) and ended up rejetting to 130 "Dyno" mains (not sure what the standard-type equivalent would be - perhaps 152 to 155 ish?) with 42 pilots. I also fitted Thruxton needles with six (yes six) shims to account for the extra response due to replacing the stock slide springs with a pair from a Kawasaki GPz900. The cans I'm using are a pair of togas with JC Whitney type baffles (only a bit shorter) which were "opened up" by having a 10mm drift battered down through the middle.
