Now granted, my 48 was never supposed to be a long hauler. I bought it and had it titled for my business for local pick-ups. I had a detachable rack installed, and found a carrier for my needs. The problem, of course, is that the little 48 is a blast to ride! So much so that I keep popping my fuel warning light on! Larger Sportie tanks could cost about 1,000 bucks figuring in paint and installation as EFI bikes have electronic connections (to which I am not familiar.) I checked the 'net for spare tanks that would fit my rack, but many look like larger aluminum fuel cells that might require a direct hook-up. Has anyone found a gas can that can be mounted to a Harley detachable rack, easy to pour, and holds a gallon or more? We have lots of off-ramps on our slab, and little burgs on Class A highway. If I could go 80 miles between fills, it would be great. Right now, at about 55 miles the warning light pops on, and I have been told not to trust it.
