Pinging when it's hot

I had the common pinging problem on my 2011, 103 T-max tuned motor, symptoms were.
- Hot engine
- Underload (like when passing or going up hill)
- Higher gears at lower rpms
- checked fuel pressure - good
Tried everything, octane made no difference, 10% Ethanol made no difference, ran some seafoam through for no difference. Cams made no difference (stock or SE 255).
Finally went with one a step colder plug, the Denso iridium # IXU24. Have had no problems since, in hot or cold weather. The recent ride, through the Smokies and Appalachian range loaded and double up in 85 degress - no pinging at all!
Best advice - get the plugs.

Depending on gear ratio, how hard you are accelerating, and the load, 2200-2500 "roll on" could still create a strain that makes the motor ping. I got cold plugs cold oil and still get a ping sometimes.

Thanks for the tip. If they don't solve my problem, I'll add fuel to the A/F mixture.

My bike had a pinging issue much more severe than it sounds like you have. A combination of more fuel and less timing was my fix. Adding fuel will only do so much. Extra fuel does not prevent pinging directly. It does lower the temperatures slightly and that is where you may benefit. Removing a degree or two of timing in the affected areas has a direct effect and is probably the most effective way to eliminate a ping.
The colder spark plugs, as mentioned in a previous thread may help, but I have no experience to confirm or deny that fix.
The severity of your pinging probably dictates which adjustment or combination of adjustments will work best for you.
