While we talk about the fuel valve, we never make students fiddle with the silly thing- we turn it on in the morning and tell them not to worry about it. One day I went to ride a demo and was *almost* back to starting point when bike died. Smug student: "Did you turn the gas on?" My KLR, for all it's cheapness, has a petcock that is both vacuum operated AND has an 'off'. I never turned it off because, hey- vacuum operated. Let roomie borrow it. He turned it off. I got two blocks... downhill... when it died. pushed it back home, changed bikes. Later that night- "Duh, you forgot to turn the gas on!" You're not complaining, you're bragging about getting to ride the Triumph. Many years ago, I made a plan to go riding with buddies on Sunday; then went out and got shit-faced falling-down drunk Saturday. Not far into the ride, I was forced to make a decision- whether to try to puke over, or under, the chinbar of my new $600 helmet. (BLARF- direct hit!) I will never, ever, ride hung over again.
