As crazy as that may sound, I remember way back when Honda came out with the RFVC engines for the XR350/500/600 there was a little cavity on the head or cylinder of one of those bikes that had a little cover that bolted onto it. Not sure what it was for, but I remember the magazines joking that it would be a good place to wrap a small potato in foil for an after-ride baked potato snack. Butter and chives could be kept in the tool pouch.
Good grief! Someone as old as me that remembers that silly comment!
That was Dirt Bike, back when it was a decent mag and not written on a comic book level with everything being described like it's related to eating (perhaps they're spending too much time watching the Food Network instead of doing bike related stuff? )
