Okay...A freezing cold six-pack of Pacifico goes to the winner: The "one best answer" that proves "definitively" one way or the other, that if the valve stem jam nut (that is provided with all new inner tubes) if used, will hide possible tube migration and that the tube's valve stem will split from the tube ending up in the dreaded flat tire scenario. Hmmm? Is this challenge possibly a what came first? the chicken or the egg situation? If one daring motorcyclist/mechanic snugs the valve jam nut to the rim, will it actually slow the progression of the tube from walking around the rim in the first place? Why do tube manufacturers add these jam nuts with the tube if no one recommends using them? Are they there just to keep the dust cap from vibrating off? If once the valve stem is secured to the rim would it actually stop tube migration altogether? Or will the valve stem depart from the rest of the tube as a general rule? Did someone back in the Moto dark ages ride his bike 25 miles on a flat, take the tube out later and say "Hey, my tube busted at that valve thingy! I bet the tube would have been okay if only I didn't use that jam nut and I gave it to Skeeter to fix his kid's bike like he asked!" Please note: any contestant answers such as: "Hey my dad and grandpa never tightened their inner tube jam nuts" "So I don't either!" or "If you would just run 30psi your tubes they won't migrate!" will be immediately disqualified from participating in the contest. This is a highly scientific, experimental, examination of Moto lore, and as such, there is an incredible responsibility and opportunity; the possibility arrises of finally debunking a very long standing Moto Urban Legend. All contestant answers will be put to a Rigger-Us challenge of being peer reviewed and third party reproduction in the Moto Labs of the Universal Church of Malcolm Smith and Roger Decoster. I'm Looking forward to all the expert science that will arise through this highly technical challenge! With greatest respect to you and your Moto Wisdom, The Lab Mule
