After spending several hours on the scuba compressor fault finding I finally manage to find the reason for the sudden loss of pressure, it was a leaking spring loaded valve in the filter housing!
Since this particular filter housing is quite old and a bit unsafe compared to newer ones (they have been reported to break and blow up according to comments on diving forums) I decided to remove it and run without a filter, I will never use these air bottles for breathing purposes so it doesen´t matter if a bit of oil/moisture gets into them.
With that headache out of the way I fitted the second Gopro camera to the rear fairing pointing backwards, I printed a rivet mount on the 3D printer a while ago for this particular reason.
Unless I manage to kick it away while mounting the bike it will stay in place.
Finally I solved a problem that have bothered me for a while, namely how to fit the towing line to the bike.
With all the fairings on the bike there is no useful attachment in line with the wheels, so how will I get the darn bike back to the pits after the race? I solved it by cutting a length of CrMo tubing that slides down the hole in the steering head, then I can fit the towing line to it above the wind screen. I use hose clamps instead of welded washers so I can adjust it depending on the height of the towing vehicle.
Cheers!
