Hey guys I have alittle problem, I have been getting about 160 miles per tanks riding which is about 56 mpg filling up with about 3 gallons of fuel. I've noticed the past 2 times I've filled up I'm running into reserve now at 130 miles, still getting my 56 mpg but only topping off with 2.2 gallons, why I'm I hitting my reserve at 130 now????? whats in the tank is it a hose? 750 Spirit
