Bingo! Crossover hose was disconnected from right tank. Thanks for the suggestion.

I checked mine today and found nothing. All hoses hooked up with no cracks or leaks. Took it out for a ride down I-70 for a ways, and then pulled in the garage. No gas smell today, but then my garage is down to about 80 deg., instead of 100 like it has been all summer. I think the gas I smell is from the gas tank vent through the vent valve at the bottom of the frame.

Once you park in the garage you may push down on the fuel cap and tighten it to a point of no 'clicks'. This will stop the vapor leak, but remember to do this !!! Before starting the bike unscrew the cap and let the tank breathe. By not doing this it will create a vapor lock and the engine may stall at any time. I know this from first hand experience. Another easy way is to take a soft cloth and wrap it around the fuel cap neck and it will absorb the fumes also.

One thing my manual is not clear on is that they call the valve at the bottom of the vent line the "vapor vent valve", and it is to be in there with the long end up. If that lets the vapors that build up in the tank when it heats up vent, does it also let air in for fuel being drawn from the tank? Or do the gas caps let air in? It has to breathe both ways somehow.

The right hand cap is vented, and only the right hand cap. That's why the two caps are right and left hand threaded.
