I changed the battery in the rear sending unit and no change, so I swapped rear units from my other Motorcycle and reprogramed them to each bike. Still no change.

The front will update as I roll the bike out of the garage. It should be quick as it is close the readout receiver. BUT the rear still takes 2 to 3 miles before it updates. This only happens on the F6B, my 78 Wing rear readout is also slow to react but not miles like the F6B.
I called Steelmate USA in California but they do not sell this system and have no tech support for it.

I suppose I will live with it for now as I feel it is just a weak system but probably will change systems before to long..
