Riding back from Dime Box, the reserve light came on. I almost missed it, because it was really pale. I had to modify my vision angle to verify that it was actually lit. I stopped at a gas station, and it is definitively difficult to see when it is lit. Compared to the neutral and oil pressure. Is it the same on your Guzzi? or does the intensity increases as you deplete the rest of the tank? I only had 1.109 Gal left which I guess means I saw it more less at the time it came on.
