Noise?

I can't discern from the video whether or not I hear pinging. But if you are experiencing pinging with the highest octane fuel you have available then there is only one cure... You have to back out a little timing until the ping is cured.
Unfortunately, the only way I know of to do that is with a tuner. I believe the SE tuner allows ignition timing changes but I'm not certain of the range. Most aftermarket tuners are infinitely adjustable.
As for the knock sensors, while they can and do help, they are not 100% effective in all cases.

Yea im not sure what it is. Was hoping dealer could pin point it for me. But there first attempt was a fail. So i dont know what to do. I would love to put a tuner and stage 1 on my bike. But im afraid with my luck it wont fix it then if i have major trouble out of it my warrenty will be gone. So i can keep it stock and continue to search for it and let the dealer look at it again. Or tune it and risk loosing my warrenty. I have been over every bolt on the bike i can get too. An still beleive if its not a engine detonation/ping its something comeing from the primary. Its for sure coming when i roll on the throttle and no other time and seems to be heard better on the left side. But i can hear it from just about any position on the bike. Octane doesnt do jack. I have felt the bike run bettter in my search for better gas but the noise doesnt change. I can tell when my bike has better gas then the last tank because it runs smoother and responds quicker. But like i said has no effect on the sound im concerned with.
If you are concerned with warranty research the SE Tuner. It will not void your warranty and it may be able to tune away the ping with ignition timing changes. I'm just not sure of the ignition timing adjustment limits of the SE Tuner... That's why I suggest you research it before just jumping in.

Knock sensors are not controlling the spark knock on some M8s. I can get mine to knock from off idle to almost redline! Just grab some throttle. My Limited gets real loud at 60mph in 4th or 5th gear when I grab more throttle.
I'm tired of letting the dealer and Harley screw with mine looking for the cause. Every time they touch it they muck something else up. If it comes unglued it's under warranty. I won't lose any sleep over it.

If you only hear the sound when rolling on the throttle, that to me is a pretty good indicator that what you're hearing is pinging.

Well i got a update on my bike. I finally got it to the dealership. One tech said they fixed it with a new ecm flash from the moco. An another tech said it was pretty normal for m8s to ping and that it would prolly continue to ping. I road it last nite and it maybe a little better but still there after they dropped it back off. I really dont know what to do now. On a good note it is documented now. Was going to order some stage 1 parts for xmas depending the out come of this but looks like i still gotta hold off. Im keeping my warrenty intack untill this is fixed.
I´m from Germany and have the same pinging / spark knock when accelerating. Because this post is a little bit older i like to ask if you have found the reason of the pinging or have fixed it by your dealer?
Thanks very much, Kai
