I have a 2001 zx1100d, I was experiencing idling problems which led me to taking the carbs off. I found that #3 cylinder was not getting any fuel at all. So now I have a tapping noise coming from engine. I have cracked the case to see if I burned a connecting rod bearing and they all seem to be fine. I don't know what else I could have done from running it with no fuel. Any insight would help.
