Hey, so I just bought a 2005 zx6r from a guy who had originally bought it from a shop called Derry Cycle. I ended up taking it to Derry Cycle for a new tire and when I picked it up the next day they couldn't get it started. Honestly I'm frustrated because it was running fine when I brought it and when they test drove it. They did say it ran out of gas so they put more in, but today when they tried starting it, it would just barely idle and then die when they gave it gas. Any ideas on what's wrong with it?
