Slasher - You should note that most IBA certificate rides require some sort of documentation at least every 300 miles, so you might as well fill up for the fuel receipt. I believe they are a bit flexible on this, especially if you have additional proof such as a SPOT track. Also on a pre-planned ride, they may look the other way too. In my experience, they have always been more than fair when it came to documented proof of the ride. But I would play it safe and not push past 300-350 miles between stops. It would suck to do the ride and not get the cert because of this. If you have questions about doing IBA certificate rides, I can help, I have done quite a few. The rule below is copied from the Rides and Rules page for Saddlesores and Bunburners on the IBA website:
WARNING: If your motorcycle is equipped with a large fuel-tank, please note that you must stop at least once every 300 miles for gas (this is purely for documentation for your ride). Although we know it is possible to ride greater distances non-stop, we will not accept a claim of this type.
Ken - I'm not planning on attending the RTE, I'm not much for group riding or crowds in general. I am looking forward to meeting all of you and doing some tire kicking and story swapping at the hotel however! I'll be wearing my name tag, so if you see me, make sure to say Hi!
