"We were trying to beat some thunderstorms across Montana and the gas cap did not vent properly, which made the mixture too lean. Plus we were running flat-out into a heavy head wind. All of a sudden, Luke, who was on his bike, and I saw an orange flame shoot out of the carburetor about a foot long. Scared the crap out of him," Wolter says. Stopping by the side of the road, they found molten aluminum in the back side of the air filter. At that point, Keith Wolter departed the group in Helena, Montana, which left an extra bike. Perhaps ignominiously, this bike spent the rest of the trip in the chase van.
