Nice work Septic, but just a quick comment on it....
The end of the pipe should be BEHIND the screen....if you do a shallow-ish ford at speed, the splash will still chuck water down the tube...plus it'll be neater (and you can make it shorter..it could end behind the NippyNorm sticker)
In all honesty, snorkels on GS's don't really need to be much more than things that stop the wash of water that comes over the cylinder heads from going down the intake.......they only need to run up to around the headstock IMO...unless you're seriously hardcore and then you'd need to seal the air box, fuse box etc.
