"tinging" noise
#82
I described it either banging on a long steel cable/wire sound, or the sound of two thin swords hitting together.
I did try a tank of 93 and it seemed to help....tried another and it's there again, but not as bad.
The funniest thing I've noticed is that on this thread, most everyone has at least 6k miles when it starts. Thats exactly when the sound showed up on mine.
I also took my bike to little sturgis rally and revved it up really tight. That seemed to help it too for a few days....funny, but true.
Maybe after some miles the engines needs to be remapped/tuned to compensate for loosening up?

if pinging is caused by pre-ignition, maybe. If pinging is caused by detonation, timing will not help. During detonation the air fuel mixture is ignited before the spark due to heat and compression.
In my case, I know it is detonation and not pre-ignition since it only occurs when the engine is hot and the ambient temperature is hot also. (probably the bike's way of saying you are crazy for being outside!)

Glydiator just made a good point when he said that his bike ran better after running it hard. Detonation can be caused after X number of miles of "light" riding due to carbon build up. That will raise compression and cause detonation. My solution has been to just keep my RPM's up. Downshift instead of just rolling into the throttle in higher gears and the noise never appears. I'm no expert but this has been my experience living in the hot South and dealing with high compression.

As I've said, mine started doing it with about 5000 miles on it. I've had the XIED's on it from the start. Yesterday I removed them and still had the problem. I always run 91 octane (highest available in my area). I have a SEST install scheduled in 2 weeks, if I don't resolve this issue by then I'm curious if this will make any difference. This is beginning to annoy me.
