My vulcan sat for quite a while before I bought it and runs just great after it starts but....Its hard to start. Ive put Seafoam in two tanks of gas now and today I drained the carbs/ carb that is as the carb on the shift side would not drain at all, nothing came out after removing the drain screw and attaching the hose and clear glass bottle to it/...I took the hose from the gas tank off that goes into it and shot some carb cleaner through it and still nothing came out. The carb on the brake side drained perfect and was super clean?? I just put more SEAFOAM in a fresh tank of gas and at the gas station I had a hell of a time getting it started again as it cranked and cranked and back fired a lot before finally starting then ran perfect back to my house...It has new plugs, runs great after getting it started and im getting 50 mpg or better riding two up at 55 mph. Thanks to anyone that can help me with this problem.
