About 10 years ago I bought a vulcanizing tire repair kit and stored it in my bike. While on an MC trip a few days ago while gassing up a rider came in and said he had a flat. Finally! (I thought) I would get a chance to open the sealed package and test my tire repair kit. Long story short.....nothing worked! The Canadian biker purchased a car tire repair kit (those wormy things with a plunger) and off he went.

Test your equipment!
