Question High Pitch Noise

Hi All,

I have a 2007 Versys and since I have owned it it has made a high pitch squeeling noise that sounds like it is coming from the fuel pump, to the left of the tank.

It sounds like it could be some sort of electrical resonance or something and I as I rev the bike the pitch does change but is always there. I have had a few garages look at the bike including kawasaki but they cannot find any fault with the bike and or say everything is fine.

this noise if driving insane as i can hear it with ear plugs and helmut up to about 30mph.

has anyone had the same experience or know of the cause or what can be done to get rid of the noise.

Thanks in advance.

Otherwise I am loving the bike.
Barny

The high pitch squealing might be buzzing from the cowling that has been addressed in many threads on here. Do a search using buzzing. Here's one thread.

Thanks for the reply. I did also have some of the buzzing noise problems a while back around 3000 RPM. I had kawasaki put some rubber washers in the screen and this seems to have cleared up the problem.

The high pitch noise is still there however and I think it is a different issue.

I do have hot grips installed and I was wondering if that may have caused the problem. I did try and disconnect them but the noisewas still present, I may not have disconnected properly though.

Any ideas.......anyone........thanks.

Thanks for the advice. I have tried these things but it still persists. Kawasaki have looked at it and can find no fault, but i defo think it is coming from the fuel pump. Should I insist they replace it under warranty?

Any other ideas or news would be greatly appreciated.

Thanks

The cooling fans emit some sounds, as does the fuel pump.

I have noticed after running the engine and then turning it off, that the fuel tank will either build up pressure or a vaccum (it's kind of hard to tell) but with the pressure difference there is a high pitch noise from the fuel cap and as sure as you open the cap the noise goings away.

The sound we all hear is the diode bridge (rectifier) that converts the AC voltage alternator output to the DC voltage that the bike needs to run on (as well as all vehicles on the road). Why it is so noticeable on this bike is that the stock exhaust at idle and low speeds is quiet. The change in pitch is directly related to the amount current draw on the alternator. This is perfectly normal and if you don't like the sound then then replace the stock can and you won't notice it anymore...maybe slightly at idle. The other sounds mentioned (fuel pump priming and tank venting) are heard before you crank up (fuel pump) and when you shut off in warm or hot weather (tank venting). Odd sounds are a normal part of any vehicle...the trick is learn the normal ones so when you hear something off normal you can do something about it.

Very interesting BayouVersys. My high pitch noise does remain all the time, with fuel cap open etc and changes pitch as you rev the bike. I had always suspected that it may have been caused by some sort of electrical issue and thought it could have been done to incorrect Hot Grip wiring.

Can I ask, do you hear this noise all the time too?

Although it all seems normal and the bike has run fine for 11,000 miles my concern was more to do with resale and I wanted to get it fixed if it was an issue before the waranty was up.

Cheers

high pitch squealing

I sometimes hear a high pitch noise around my bike also. This has happened with every motorcycle I own. Sometimes happens right when I come back from a ride; sometimes when I am just lovingly waxing it, or tinkering.

I have noticed that the sound goes away as soon as I get on my bike, start it, and drive at least a half-block away from my mother-in-law.

Sorry for the late reply Buffty, yes I do hear it only at idle. When I turn on my fork lights the pitch changes from the increased current draw. All seems normal
