Nice gauges, and not too expensive. I really like the idea of the GPS units, they tend to be more accurate, although with all Campbells tunnels, I wonder what they do then?
I share your pain, my monster wheel (2001) has a speedo drive. So will just either leave it as a spacer or replace with one. I am going down the motogadget gauge path (pictured) as I wanted a single tacho with an integrated digital speedo, and I like their solution the best. The speedo runs off an electronic pickup and can be calibrated, so I'll mount it to pickup the final drive sprocket bolts, or disks if that doesn't work.
