Dong Fang DF 250 RTB Bobber Information

[barnone]

Not sure what my mpg is, but Im going to be able to begin to make observations on it now that i don't need to let it sit and run idle.
but thats a number with limited use until we know typically how far into a tank the petcock is.

that said, I forgot to calculate the return trip back from last fill up, so my number is about 105 indicated until a refill is needed.
I drive in limited suburban traffic with very little sitting and moderate amount of stop and go. but that's all very subjective.

axa,
Normally the "reserve" position on the petcock on a motorcycle does not have much of a tube sticking up in the tank like the "on" position has so you should be able to use almost all the fuel in the tank.

This one is a vacuum operated petcock but the manual ones like the DF's have a similar setup for the fuel inlets.

I have not had the petcock out of the 2012 DF tank but every other one that I have out on many bikes including my long gone 2010 DF did not have much of a tube sticking up for the "reserve" position. Usually just a bit in order to attach a filter sock on it.

When she sputters (the petcock is in the "on " position) I switch to the "reserve" position and get gas at the first available station. Of course if I am in an area where I don't know where the gas stations are located then I fill up sooner.

Also as a rule, I do not cut it close on gas in any of my vehicles.
