Hey folks, so I recently bought an '03 Vulcan that has probably been sitting for 6+ years. PO said he drove the bike from the place he bought it to his house, parked it, and it's been sitting since. Been having issues with it running properly. Once I got a fresh battery in, she started, but wouldnt idle properly and would bog down and die when trying to rev. So I cleaned the carbs, replaced spark plugs, oil, and air filter. This fixed some of the idling issues, but still wouldnt run when at half or no choke. Took her for a couple test rides to see if it would smooth out, had less than 10 miles on it before backfiring and dying. Now it wont start and when I do try to start it, has a clunking sound coming from the right side. Before the most recent test ride, had a hissing almost tick sound in tandem with RPMs that wasnt there before. When riding, throttle was sluggish or even bogged down when trying to speed up at low RPM, often stalling out. When taking turns, wanted to die then as well. I was thinking it's a fuel issue before, but now that it wont start at all, I'm not sure what to do. Probably made it worse by riding it. Any clues?
