Engine noise I'm noticing under acceleration
New owner of a 07 KLX250S with 4k miles. During a ride around the hood earlier tonight I noticed a noise that sounded a bit odd. It's a kind of rattle or light knock when the bike is under hard acceleration. I've experienced ping/detonation on several bikes but this doesn't sound the same. The engine almost sounds like a diesel when the noise occurs.
Bike is mostly stock. It has a K&N air filter, stock carb & exhaust. As far as I know a jet kit wasn't installed.
What could the noise be if not ping?

Yes, though I can reproduce it in pretty much any gear when rolling on the throttle at a lower RPM. The engine sounds tight at idle. There is a little valve tappet noise but that is separate from the diesel-sounding noise I'm hearing.

Nothing has changed on the bike since the sound started?
Did you just install/reinstall a skid plate?
Sounds like my skid plate without and double sided foam tape stuck between the frame and plate.
