I've noticed a singing noise from my engine, or possibly a super fast chirping. The frequency changes with engine RPM. Any ideas what I should be looking for?

If it makes the noise while on the sidestand, I would try to locate where the noise is coming from using a stethescope or a long screwdriver pressed to the ear and touching various parts of the engine.
Drive chain has a tight spot. Loosen chain a little or replace. Does it happen with the clutch in & coasting.
While sitting in traffic I can hear it a little, it's a lot easier to hear when engine rpm is around 3k-4k. I make it a habit to not rev the engine on the sidestand.Originally Posted by Sparky
It's not the chain whine. Chain whine changes with speed; this changes with engine rpm, regardless of speed.
Intake air noise.? Loose hardware on fairings or plastic and harmonics are just right to chrip at 4k. Check air filter maybe clogged and it is singing to you through a little air hole.??

Sounds normal to me. Sound like cam chain noise to me. Check chain adjusters.
Sounds normal to me,also . sounds good !
EBR intake noise. Sounds clean.
I probably just didn't notice it before, then.
My air filter was dirty af, though.
Started engine with airbox cover off, still made whirring noise. Probably cam chains as Kid Thunder pointed out.
