RE: Engine Pinging
Actually it should be worse in WARM weather.We need to think about this since the problem started in the fall.Solving your problem may benefit all of us.Is it possible that something is loose and vibrating under your tank when you accelerate?As you well know these rubber mounted engines vibrate at different rpm's.

It is a ping, it it won't ping if I down shift unless I jump on it hard. I seems to be worse in cold weather. Around here eastern NY, western Ct area I have yet to find a gas station with a separate fill for premium gas.

My owners manual does not say pinging is normal,in the back of the book there is a troubleshooting guide QUOTE:PRE-IGNITION OR DETONATION(KNOCKS OR PINGS) 1.INCORRECT FUEL 2.INCORRECT SPARK PLUG FOR THE KIND OF SERVICE. Believe me detonation will destroy an air cooled engine if severe enough.

Yep!
I've noticed it since day one and I can hear it every time I am heavy on the throttle. I think the owners manual says that it is normal. I disagree!
I'm sure it has to do with the extremely lean map that they are running stock. My dealer wouldn't even look at it and said it was normal. I have even tried Sunoco 94 octane and it will still ping. It is one of the things that I am not that impressed about for a NEW motorcycle. I like fuel injection, hell I teach fuel injection as a profession, but I sure like my S&S carburetor and pipes that were easy to tune and didn't give me any hassle.
