leave the petcock on reserve ?

Ive set the petcock to reserve and just leave it like that, the thought being it prevents old gas from pooling at the bottom of the tank. Is this a myth ?

I was going to say I pay close attention and go to the gas station at 100 miles like clockwork but I did once run out of gas on the side of the interstate in Missouri. State Trooper picked me up and drove me to the nearest station. Good people out there in Missouri

Leaving the petcock in anything but the off position when parked can allow gas to make it's way to the crankcase, diluting the oil and washing the oil film off the cylinder wall if the float valve leaks/sticks.

Keepin' all the left over parts. Gonna use 'em to build another bike!

When my engine starts to sputter, then I'll flip it to reserve and note what my odometer reading is. I know I have at least 30 more miles before I'm out of gas. I also flip it to reserve for a few minutes if the bike sat out in a rain. More than once it sputtered because the gas had some water in it.

One thing that leaving the petcock on reserve did for me, is to re-affirm that I do NOT like pushing a bike, no matter how 'light' they are.

To save starting new thread. I left my petcock turned off the other day (we've all done it) and after a mile or so it spluttered, so I turned it on and the bike as expected went on it's merry way!!


Yesterday I did the same thing again, but never realised as it drove just fine. I probably did at least 10 miles. It was only when I stopped for coffee I noticed the petcock was turned off.


Kind of hoping my petcock isn't shot as I need to take the tank off soon! Surely on a carb full of fuel 10 miles is asking too much!!!

Sounds like the petcock isn't working as it should. You can put a 250 petcock on your 450, but of course you loose the vacuum actuated feature.
