Hi I need some help, someone gave me some bad gas so I tried to siphon the tank and couldn't so I pulled the drain plug. It sat overnight because I couldn't find the the plug witch had fell into a groove. I put a gallon of gas and now the bike wont start. all the systems are working I hear the pump start, it cranks, but its not pulling gas. Do I need to prime something, and if so how do I prime it? Youtube is no help
