Wind noise....Thank you

[Fergie in France]

On the 30th July 23 TRIGGER51 wrote about a wind noise coming from the front, suspected wheel bearings . I had checked, bearings, calipers, speedo drive, rad cover, mudguard, cables,  brackets, inserts, you name it, i checked and cleaned where nessassary, plus a road test inbetween each job.

All to no avail, it was still there driving me nuts.

On the 31st BBROWN1644, repliedt to TRIGGER,  possibly tyre, remove mudguard and test. It was a last ditch attempt, never thought it would work,.. it did, no noise.... 

The Bridgestone 023 has only done around 6000kms, I've has then on a Sprint, XJR1300, and now my Fazer  without an issue, a great tyre, until now.....

I'm almost 80, had bikes since l was 16, worked on everyone I've ever owned,  thought l knew most things,  but,  lesson learnt, always come on here first to see if someones had the same problems 

So a thankyou to Tigger for posting, and BBrown  for the answer....

Regards Fergie

its just the tread pattern causing the noise due to the airflow it creates under the mudguard. Put some ear plugs in and enjoy the ride.

Close inspection ,with the wheel off the ground and spinning, you can see a slight wave pattern, as it wasn't doing it aroind 400kms ago I'm going for a new tyre. I maybe getting on a bit, but l can still hustle the old girl around, no chicken strips (rear) that and the hot roads recently haven't helped perhaps ? In the meantime, as you say, l will just wear ear plugs knowing its not a serious mechanical problem.. Thanks for the tip..???

The front end on my Fazer sounds like a kid's zip line ride !! I checked my front tyre and found uneven wear each side of the centre line. I read somewhere it is called "cupping"

Have you done anything about it, like changing whatever model of tyre it is?

On a side note, the noise you're describing can also occur if you do any adjustment at all to your rear wheel. 
If the wheel is aligned differently by the smallest of margins the chain can rub against the plastic chain guide causing the noise you're talking about.
It goes away once it's settled down after a few weeks and has cut a new path, but it can sound fairly loud and annoying for a while, but wll also take you by surprise if you weren't expecting it.
This noise is especially common for a while if you've purchased and fitted a wider/heavier duty chain than before, or for whatever reason replaced the plastic chain guide.
Your "zip line ride" noise description is pretty much spot on as a comparison.
