whine

[s.ga.rider]

So what in the fjr power plant actually makes the turbine whine sound?

 

[Proteus1952]

Good question. I've wondered myself for over 2 years. Looking forward to possible answers.

 

[MrZappo]

Gotta be the gearbox I would think. I'd you need more accuracy than that, you will have to wait for someone smarter to chime in.

Strait Cut Steel Gear's????????????????????????????????????????/

I'm not smarter than anyone!

I have never thought mine whined.

I always thought it said MORE!

 

[garauld]

I hear mine more when I use the large barn door windshield in cold weather. I hardly hear it with my earplugs...

 

[redzgrider]

Whine while rolling at speed or when stopped at lights and such? My fuel pump whines far more than I appreciate whenever I'm stopped. Dealer, of course, says that's normal...

 

[Bustanut joker]

An empty bottle of wine stuck someplace?

On the Gen 1 motor, the only straight cut gears are the ones for the counter balancers. I can't say on the Gen II or III. But that would be my guess

 

[s.ga.rider]

Mine whines at idle or on the road. Not the gears and my 07 was the same.

 

[hppants]

Huh?

If the motor is running, the counter balancers better be turning.....

 

[Bustanut joker]

I'd sell the damn thing before it blows up

Yup, there's a couple [older] threads on the subject and the balancer gears were identified as the source of our beloved turbine whine.

Whine is Japanese for varoom.

I just checked my oh-fishal Yamaha Service Manual (GEN1) and it looks like all the gears coming off the crank are of the straight cut variety... aka "spur" gears. IMO, the primary gear (crank to clutch) is the main source of the whine and this very common for motorcycle engines. The balancers spin significantly faster than the crank so they may contribute as well. Either way, it a great sound and not intrusive at all. My ST1100 had a very pronounced whine (so does the ST1300) and folks sometimes complained about it!

<sarcasm>If only there were a technology to conveniently review all the times somebody talked about "whine" on the forum...one would think the scholarly could solve this enigma. If only we could understand the inscrutable reason it was moved to NEPRT. Humanity suffers in the meantime and wonders if Google could possibly help.</sarcasm>

I'm with Bustanut on this one. I'm gonna have to teach some non-optional search classes one of these days for a few folks.

Little known fact: The FJR engine actually does have a turbine in there

 

[Uncle Hud]

The throttle.

Mine spins up like a Navy gas turbine when accelerating. Like the sound effect in a Batman movie. Brings forth a gentle smile when I hear it.

 

[BanjoBoy]

Mah wife/sister, (Banjo, I'm cold, I'm hungry, I'm too hawt, lets stop at that fruit stand...) or maybe the counter balancers?

 

[s.ga.rider]

I like he whine to. Its been unique compared to my other bikes. Thanks to the ones who explained some of the reasons why.
