Hello, I just bought a 2007 Suzuki boulevard c50 from someone who kept it in a garage and did not ride it for 3 years. Right after I got it, it started to spit and sputter. I changed the oil, radiator fluid, had the fuel injectors cleaned, replaced the fuel pump, cleaned the spark plugs, etc. We have tried everything it seems, and the bike is still sputtering, especially at low speeds. I’m wondering if maybe it’s an electrical issue? This is my first bike (aside from a Honda Rebel I rode for two weeks). Please help!!!
edit: I can’t get it to idle at the start.
