Any news on this? I have the same issue with my left cylinder, and I was worried that it was possibly a bearing but then I felt the expansion chamber on that side and I could litterally feel the sound, Which now is making me think that cylinder is leaning out which is causing some detination. After thinking this it did sound alot more like a "PING" then a "knock" So I'm keeping high hopes. and plan on ripping the carbs apart this weekend to give them a good clean and make sure my jets are good.
