When on the road and you would need to inflate the tire/s, he would just turn the gas fosset to off and then kick start the bike. Of course it would not start, but after a few kicks, the tire is inflated
The above has nothing to do with the tool, but I think it's a funny story, worth mentioning
Sure; they've been around since cars first appeared, and work great! If the engine is more than
1 cylinder, it will run while inflating. If one cyl, it pumps while kicking or spinning the starter (provided
there's no automatic compression release) With 150psi on tap, it only take a moment to inflate a tire.
I carried one for years, and still have 2-3. They use fresh air valves, so no gas-laden air goes into tires.
Perfect for use with airhead BMW's, as the cylinders/plugs have easy access and run ok on one cylinder.....
