Hi


A VT500E puzzle


I have a whooshing noise on my VT500, It sound very similar to the cooling fan coming on


I can hear it mainly at about 30-40mph however when stopping to have a look it stops.

The sound remains constant even if I pull in the clutch, increase the engine speed, or slow down :?

I have blocked up all vents the, wedged paper in the fan to stop it turning, move the horn and even changed my lid (just in case)


no idea what it is has anybody else come across this...!


thanks

wilf :?

Is it chain or shaft drive? could it be related to that at all :?


seems odd


what about taking it out of gear and switching it off to try and pin point it it might not be engine related


off road of course :lol:

It's shaft drive


I've tried changing up and down gears as well, still there.

The noise comes and goes so I've ruled out wind related

the other option is to try running it in gear whilst on it's centre stand - but only on a straight road whilst on it


I'm suspecting water pump or clutch but cannot understand why I wouldn't hear it whilst running in neutral

What condition are your tyres? Worn tyres can cause more road noise. Also, what condition are your wheel bearings? Worn or Dry bearings could cause some noise. Also check your disks and pads......all stuff that are more related to road speed than engine speed..... :wink:

The tyres are in good condition about half way through their life


the front wheel bearings were replaced not so long ago and the noise still persists even

when applying the breaks either front or back.


i'm stlll puzzled :?

Sounds like wind noise,, If the bike runs ok with no other problems,, why worry :wink:


I would worry about stopping a fan turning, its liable to burn out :cry:

 

:stupid:


I accidentally stopped the fan on my Speed 4 when I had it.......took a fuse out and brought on the MIL light......Doh... :roll:

The fan shouldn't run all the time anyway....especially this time of year......mine only comes on when I'm stuck in traffic at slow speeds.... :wink:

Checked the front disk all fine (yes brakes are crap but I look at it as a learning experiance)

I noticed the noise because it sound so like the cooling fan but the bike was cold.


Had the bike running in 3rd on the centre stand and there is a vibrating from under the fairing could be this?

nothing else


not had chance to try the switching off the engine trial yet weather has been crap :roll:

Could be that something is loose on the fairing which is making it noisy at a certain speed. I'd go right the way around the fairing and all panels and check that they are all tight.... :wink:

Finally got the chance to try the switching off the engine suggestion.

Noise still there, so I guess this points to either wind noise or the front wheel

I'll check the carbs suggestion next

thanks

when I first read it i thought wind noise too

close your helmet :P - but on a serious note, are you sure it isnt the helmet? The linig may have stretched just that little bit over the last week allowing wind noise to reach your ear through the side panels or chin skirt


as for the bike, does it sound like the wind or vibrations? My right fairing has just started to vibrate when warming the bike up, and the screen vibrates at a certain rpm


You could try just holding random parts of the bike to see if its that bit vibrating and check things are tight and not cracked. I was riding with someone who hit a large pot hole and cracked the front cowling mounts and the rear end mounts, all his body work was falling off by the time he got home, but we stopped a few times with him complaining about the noise before we figured it out

If you've turned the engine off it won't be the carbs now will it?


I think you're trying to solve a problem you don't have. I believe sky divers get a wooshing noise as they jump out of the plane.


Get some ear plugs 8-)

thanks for all the suggestions


So far I've tried and checked all suggestions without luck. yep changed my lid it was the first thing.

more of a whirring than whooshing sound that why I thought it was the cooling fan.


got no idea, has been suggested at the bike club it's the gear box, I'll not going to bother checking that

just wait till it breaks.


:stupid:
