I've had them on my XJ1100Maxim and other XS1100s..On the maxim i would run the bike with petcocks in "on" position...when the level in the tank dropped the engine would stutter but still run...indicative of the time to turn the petcocks to "Res"..
On my XJ is was a pretty smooth transition. As soon as the petcocks were turned to "Res" then the engine would pick right back up where it left off... On my XS1100s that transition was always cold blooded and i would actually have to pull off the road to wait for the gas to flow once again..Instead of using the "on" position..i would fill the tank up and leave the petcocks in "Res"...I would always be aware of the Odo readings for tank range and would avoid the cold blooded transition from "on" to "res"..
So my question to you all is about how you use your XS650 petcocks while riding.?
Do you all turn them to "off' when you park the bike in your garage..shed..house..what have you?
My inclination is to just run the bike with them in "res"...as for when its parked..not so sure...
