Possible Detonation & or pinging
This past weekend, riding up in VT, I had some pretty consistent but fairly mild detonation and pinging. Happened across a couple of tanks of gas, octane was 91 or better. 2011 RGU Ultra.
For the most part this occurred above 3K, typically when under load climbing a hill. Temps were hot, anywhere from 88 on up to 92 degrees, and we were riding 2-up. Motor is bone stock 103.
Is this "what it is", or is something not right? Suggested fix? Not looking to modify the intake or exhaust though.
Thanks in advance.
