A question: I have a 2008 c50 Tramp Trike. I can only get about 120 miles on a tank of fuel when the motor shuts off but when I fill up I still have over a gallon of fuel in the tank. Is there something that can be done so I can get the use of my full tank of fuel. My wife and I love the trike but we have to keep watching the fuel gauge and worry about finding a gas station. Any help would be appreciated. Thank you, ride safe.
