I've got a 2002 Vulcan 1500 Classic with Fuel Injection that I am having trouble with. It runs rich - the plugs are black (slightly) and I can smell gas fumes when it's running. Occasionally, it will not start and I can smell gas likes it's flooded. I have to let it sit for a while before I can get it started. When it does start up, it idles high until it warms up and then it drops down and stabilizes. It runs great, though. Can anyone tell me what could cause a digital fuel injected throttle body to run rich and / or flood? Or at least how to begin diagnosing it? I'm more of a carburetor guy, so I'm lost on FI.
