I didn't reset the valve on the front tank after filling it. I always run a gallon or so out of the front tank and then switch to the back one to run it near empty before switching back to the front. Since the back tank has no reserve valve I feel safer running the last part on the front tank. Doesn't help though if the reserve is on and you get to the bottom.

Jack,
Are you running a stock petcock (with vacuum) on your primary tank? I fitted a 2 gallon aux tank on the back of my bike with a T adaptor on the main fuel line, and a cutoff between the aux and the T. I'm using the stock petcock with the vacuum and I end draining the main tank before the aux tank. With the stock petcock, there is no true "off" setting. I'm thinking I need to change the petcock or add a cutoff.
