My bike has started honking at me wtf?

[Wonko The Sane]

Didn't do it / notice it yesterday but at 5500rpm my bike seems to be making a noise that sounds like a truck horn in the distance but doesn't do it at any other engine speed.

By holding the revs constant I can make the sound for as long as I can hold the throttle constant.

It's not related to road speed as ive done it in 1st and at motorway speeds.

Any ideas.

Bike has a double bubble screen fitted so wondered at first if it was wind vibration.

The bike did get rained on overnight as I forgot to put the cover on it but don't see how that can have affected anything

I don't know what that could be, have you had a look for any obvious loose screws? Particularly around the screen, that can rattle for me and make some noise.

Sounds like something resonating at the engine vibrations at 5500rpm.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Whistling of air through the airbox?

[Andyk]

maybe a dumb question but does it do it when the bikes stationary or just when its moving?

Various bits of my ZZR used to rattle at different revs but that was mostly down to half the fairing lugs being snapped/bodged/damaged. I think the bungee strap theory is a good one. Failing that, go and check for loose screws.

As posters above have said, sounds like something vibrating/resonating to me. I had a rear fairing that wasn't screwed quite tight enough that used to do it.

just been out to fill up with fuel and found it still does it,

thinking it must just be the plastics.
