We have a 2011 rt limited, new to us last Aug. Never concerned myself with gas mileage, just filled it and road with a smile on my face. Previous bikes, in the 70's & 80's, had a pet cock to turn for the reserve gas tank to kick in if you 'forgot' about filling the tank. Does the spyder have a reserve in the gas tank? I have few times risen and by not looking at the gas guage, found it to be at or in the red. Never ran out, but was wondering if the guage shows E, is it empty or does the reserve kick in?
