My bike seems to be pinging still when opening the throttle. I've searched around the forums and the answers range from "this is normal" through "add a small amount of seafoam or lucas oil stabilizer to the oil and run for a week" to "I found a cracked piston"..... I am running 93 (I know it only needs 91 - just making sure the fuel is not the issue). I also read that the valves fail over time by getting tighter vs more loose, so it's unlikely that it's loose valves, especially at only 12k miles. I know the sound is not injector ticking - you can hear that at idle. I've run techron through the system to clean it. I'm running 15W-50 full synthetic from a recent change. I do need to change the plugs to eliminate that as an issue (slight stumble at idle). So my question is, should I consider trying a small amount of seafoam in the oil (as has been suggested on this board) or lucas oil stabilizer to see if it helps? Oh and oil level is perfect too, and it's not an issue of the oil filter gasket etc as I did the oil change and made sure. I also know it's not the helical gear noise at idle. It really does sound like pinging, again, only on throttle application. Thanks for any thoughts you may have.
