Bike History?
Wheelies?
Ever down in its side while still running?
It's been all good. I've taken good care of her for the past 14=K miles that I've had her. Routine oil changes, no real issues with the history except this.
No wheelies, the only time I've been down was during slow speed U-turns when I was starting out-- but that was 3 years ago.
This problem started up a couple of months ago and I thought that higher octane or a detergent fuel would clear it up, but it hasn't.

What is your typical ride? Is the knock regular and constant or intermittent? Is it a thunk or a ping sound?
A quick way to get rid of carbon buildup (one possible cause of pinging) is to start the bike and warm it up. Have an old Windex or similar spray bottle ready with about 1/2 pint of cold water in it. Raise the tank, remove the air filter, start the bike rev it up to around 2,500 to 3,000 RPM and start spraying the water into the intakes. Reinstall the filter, drop the tank and go for a ride.
My rides vary, but the most common one is to work. Twenty miles each way with the first 2 miles being slow speed, uphill, curvy, through neighborhoods. This is followed by about 18 miles of highway speed.
As far as sound-- it's more of a thunk/clunk than a ping.
It is regular-- happens just when I am giving her some gas at the lower speeds-- even in first, or when I'm changing gears from first to second and slower speeds.
I also thought it might be that the rpm's were just too low, but that wasn't it, either.
