on a standard vacuum style petcock:
ON or RUN: vacuum from the running engine opens the valve to let fuel through, the fuel pickup tube for this is about 2 or 3 inches from the bottom of the tank, and when you shut off the bike's engine, the valve closes automatically.
PRIme: this position bypasses the vacuum system and allows fuel to flow. Use this position if you completely run out of gas and need to refill your carburetor bowls.
REServe: this position works exactly like RUN/ON, except the fuel pickup tube is at the bottom of the tank. The difference between ON and REServe is usually about half a gallon or so enabling you to get to a gas station. -

I had the same question, but the arrow on my bike ('85 GS550E) is pointing UP!!
Has my bike entered an alternate universe? (By the way, the knob on the petcock is plastic, not metal like the pictures of all of the petcocks that I have seen online.)

wort, if you enlarge this fiche, you can clearly see that the lever does appear to be plastic and, like all GS petcocks (without the large round knob and except for 1980), up is ON forward is RESERVE and back is PRIME.
Note: BEFORE taking any advice from forum members, check out which ones screw up everything that they touch yet still offer advice to others.)

Thanks for the quick reply. Mine has the large round plastic handle. It rotates from up to back to down. It can't go forward.
Thanks again.Comment

Could this be your model? (Zoom in on the cover for fuel petcock position settings.) http://www.partsoutlaw.com/oemparts/...r-gs550es3-eseComment

That's it! My bike has been painted, so there are no markings like that.
