2018 NC750X,6000 miles,stock no engine or performance mods. Stock air filter. Bike runs fine but I am hearing a pinging sound from the engine whenever at full throttle. Sounds like pre ignition or detonation which I'm told can be very harmfull to an engine. Ive tried all kinds of gas , from Sunoco 260 to regular to non ethanol. Not much difference. Has anyone experianced this?
