Venture engine sound

[alwrmcusn]

My 2009 Venture (Hannigan triked) has started making an odd sound. This will surely cause some "witty" comments but here goes.

As I accelerate and ride the bike makes a sound that I can only describe as emulating an FJR or and FZ6R (I've checked and I do still have the original Venture V-4 engine )

So it still has the normal Venture sound but there is also the other sound. I have no loss of power and gas mileage seems to remain the same. I'm guessing that I have an air leak somewhere maybe? It's not overly loud but it is noticeable to me.

[etcswjoe]

can you narrow down the location of the sound?

[alwrmcusn]

Not really, but it seems to be up front, perhaps between the front of the tank and the fairing. Of course the fairing will redirect the sound back to the rider. That's kinda why I think there might be a hose suckin' air somewhere. It isn't very loud but it is noticeable (at least to me). I'm not real sure how to describe it except to say it seems to me to sound like a sport bike that is very quiet accelerating, sort of a whining vrroommmm. It maintains the level of sound as I maintain speed. That is, as I speed up it sounds as though it is accelerating and when I reach cruising speed it holds that level of sound. I have not had any problems, have not been under the tank. It actually sounds rather nice as I'm riding but I fear something is not right and I'd like to find and fix it.

Sounds like that typical tranny whine that the Venture is famous for to me...especially when cruising. When you let off the throttle, does it go away?

[spear]

Increase the volume on the radio.

It'll go away.

[dingy]

It won't be vacuum if the level increases during accel. and then stays the same. Vacuum would change depending on throttle position/motor loading.

I don't think its transmission whine, though I could be wrong, I was once before (smile). It only started a couple of months ago. I'd have to take the bike and ride it to be sure, but I believe it maintains sound and volume at cruising speed, but I believe it dies when I roll off the throttle.

Boomer lives close enough we might could meet and have hime listen to it if that would help. The east Tennessee area is getting ice/snow tomorrow (Fri) and I have a STAR meeting Saturday, but Sunday/Monday etc I'm available if he would like to give it a listen.

Sounds like a possible lose windshield or front air deflector. Worth a check.

[Caveman]

I'm betting on the whine or the chirp. My whine got better after a clutch basket change, but then I was able to hear the chirp. Does'nt bother me at all like the whine did. Good luck.

[CaptainJoe]

did you change your oil right before you noticed this sound?

 

I once put in yamalube 10w40 and it whined like a banchee... noise was really noticeable in a certain range of about 15mph. say from 45-60 mph. At 70 mph couldn't hear the whine at all

Put 3000 mile on her and changed back to 20w50, no more noise...

[alwrmcusn]

Thanks for the replies. I think you have to actually hear it to separate the various suggestions for possible causes.

[CaptainJoe]

I'd go about it this way:

If you squeeze the clutch in at speed and the noise is still there it's not the tranny or clutch basket. tranny noises generally get louder when you apply throttle.

 

If you then (with the clutch still in) hit the kill switch and the noise is still there it's not a vacume problem either.

 

 

 

Tires on these bikes can also be loud.... I went with Dunlop E3's and they are definately noisy... My dunlop 404's were quit.

[alwrmcusn]

I feel very sure that I'm able to tell the difference between windscreen/lowers noise and tire noise. So I'm positive I can rule those out. Weather here in east Tennessee has cleared so I'll be able to get the bike out over the next couple of days and try some things out.

Where in east Tn? I am in Erwin

[JohnT]

At certain RPM's mine sounds like George Jetson's "car". Is this like the sound you are hearing?

[dacheedah]

Its the cassette player, change the tape

[Guest scarylarry]

As boomer said it could be the clutch whine..

 

Also, this is a long shot but it could be the tires depending on the brand, I have ran E3's and got a whine from hell from them it was the only set that did that and it did not start off that way..

 

I narrowed it down to the tires cause I could lean the bike a little and it stop..

 

Like I said it is shot in the dark on it being the tires, but clutch and tires would be my first to things to look at...

Now thats Funny!

 

Probably Axel Rose of "Guns and Roses" ?????

YOU COULD BE MINE, perhaps?????

Now thats got a lot of Whinning in it....

HA!

[CaptainJoe]

Ever find out where the noise was coming from?

[Drreb]

Headset turned up loud and loud pipes will take care of it I'm thinking....

[MikeWa]

Ok hold it up next to the computer and let us listen to it.

Captainjoe: I have not figured it out yet. East Tennessee has been very cold, icy, rainy and snowy. Also trying to isolate sound while riding with a helmet is rather difficult. It does rise and fall as I go through the gears and again as I indicated before my best description is that (to me) it rather sounds as though there is an FJR matching my speed/gears but that the FJR is superimposed over my Venture. It is not very loud and it does not seem to be affecting operation of the Venture.
