The IBA's 50cc Quest rules (http://www.ironbutt.com/rides/50cc.htm) gave a link to a planning web page that had been around for years. In wanting to pass the information along to another rider interested in this ride recently, I found that web page was gone.
My suspicion is it suffered from the same fate that prompted Spotwalla from no longer using Google Maps as their default mapping display.
I can manipulate GasBuddy to do a similar trick. I own a Goldwing, but also a Civic. If I plug in the vehicle as a Civic, leave the highway MPG at 36 but then change the fuel tank capacity down to 7 gallons, this will approximate the results for my purposes for a trip like the Coast to Coast 50cc Gas Stop planner. Yes, I know that the Goldwing holds less than 7 gallons of fuel in stock conditions. Rounding this up - in my use case - will plan stops more to use five or even six gallons at a time. Tweaking is encouraged.
The Gas Stop Planner actually had the capability of generating a GPX file of the output, which I never used.
Since the GasBuddy algorithm is manipulated to find the cheapest gas at a given location, it may not always plot a stop in an IBA-style 'preferred' location (same side of the exit, close to the Interstate, etc.). Thus, like any other trip planning methodology implemented, your results may vary - a lot.
Anyway, thought I'd pass this along.
There is also a Coast to Coast 50cc Gas Stop planner put beautifully crafted by Martin Frankford: http://roadtrip.apehangers.org/maps/50cc.php"
