Bean I need her phone number!!!

I'll trade you for hers???

Man Wolf, that is some serious ghetto booty there...lol!

This is one for the HubMeister, I'm starting to wonder if that high frequency whine on my 6R is coming off my regulator/rectifier (R/R) unit. There is a factory recall on the '09s, the Mothership will replace the R/R free of charge due to premature failures, I never took mine in for the recall. Hub, you ever seen an R/R go bad and make the high pitched whine? Sounds just like a teakettle whistle, been listening to it and it's sounds like way too high a frequency to be tranny or pinion gear whine. Just a thought.

I'd disconnect it. See if it goes away? You'll just run total loss for a few minutes. Won't hurt a thing. Disconnect the stator connector [3 yellow wires usually] so the buzz is not induced. Then hook it back up don't forget or then heat sets in and then there is a problem. And if there is a recall = Do it!

Yea, need to take it in.

Nope, the voltage regulator would not have anything to do with it. I had mine replaced as part of the recall. It's the little ribbed gizmo located within the right panel next to the engine head. The new one is getting just as hot. Seems like wasted effort to drive to the dealer and spending your valuable free time.

On the '09s they're failing and taking out the battery if the R/R fails to the high voltage side. Probably best to get it changed out and Mother Teapot pays the freight.

I don't think that is the source of my whistle but diode rectifiers can make a high pitched whine in faiure mode.

This whistle is driving me nuts, it's louder than my exhaust and I can't figure out where it's coming from.

You wanna hear high pitch, try the R when it coasts at a certain low speed/rpm. It's so digital, it gives me tingles listening to it.
"It all boils down to who to remove?" You can start with each sensor, throw a code, run in limp, found the noise, now watt? We are sitting on computer bikes. We are hearing circuits run that frequency pitch. The abstract in the video said, 'if you want to learn about nature, start with frequencies' or something like that?

I think it's the IAP sensor. I dropped one on the ground. Worse thing you can do with glassilicone. It's crystal in tone is what it sounded like to me: on that initial bounce? I sort of combine the lift factor, the pull on the crystal in that sensor that moves with vacuum. So I might conclude it could be the IAP?

Because of its crystadigitonallifting action. I'll start with this frequency and take a guess where it's coming from the R.

This whistle is driving me nuts, it's louder than my exhaust and I can't figure out where it's coming from.

And we have to now pinpoint it. So the question is: Do I whistle at every rpm, or do I whistle at a certain rpm? And does it go away on accel? And does it reappear upon lift? And if upon lift, is there an rpm range noted?

In the mechanical aspect of it, we want consistency is the wear. Like, good bearing/bad bearing. Say we hear a noise? Steer the car right it goes away. Steer left it comes back. We hear 'thrust' on the one worn bearing, then no load to it and it goes away.

Are we in mechanical constant or digital intermittent [comes and goes] and that means sometimes you hear it, or all of the time you hear it?

Hear it everytime in every gear Hub, only under load, lift throttle and it's gone. In neutral, nothing. Increases with engine rpm in frequency, seems too high a pitch to be a gear backlash whine but don't know for sure. After a certain speed it get's drowned out by the wind noise. It is a whistle, sounds just like the ones you used to blow on when you were a kid, starts low and then goes higher and higher as you wind out the gears, lift throttle slightly and coast...gone.

You're not saying it's intake vacuum tunnel pitch? That air sucking into the ram chamber? That's a wicked high pitch if lift kills it, load brings it on. I used to go sit way at the end of the drag strip so I could hear the nitro dragsters intake scoops make that whistle noise. It's linear and then stops just like that. Like, WH0000ooooooooooop!

If you sat downwind of me... That is

I thought of that, might be intake resonance of some kind.
