Chirps from the engine while under load

[sonny]

I love the chirping. First time i installed the ramair and rode off i stopped and nursed the bike back home. Figured i had really screwed something up. Got on here and found out that it was normally. That was a few years back. Now if it does not chirp i figure something's not right. time to balances the throttle body's.

I dont have 2nd throttle plates or the shaft, throttle bodies bored and it does it, ram air, just like he explained its the beginning of 2nd3rd4th5th if you give to her good at the beginning of a gear she chirps fades quickly once you climb in rpms, thats how mine does it. A little unnerving but as stated above, normal.

Luckily all my high frequency hearing is gone, I don't hear the crickets

And this may be why I do not hear them myself; I have no hearing in my left ear above 10K hZ. Dang M-60 took it away...
