Well, I'll show you what I have...
Taken from page 2, you have a pic of the spine and throttle bodies - one has a JB Weld stick putty to close the gap, (which is far from optimal as it doesn't allow for flex and vibration absorbtion)...
...and the other has a 90 degree PVC bend wrapped in a long strip of rubber, so keep it air/water tight.
Sorry - didn't take pics of the finished product.
Off the back I welded on a tube, and put a foam filter on the end. Ideally, it would be enclosed in an airbox so the back wheel wouldn't cover it in dirt.
