Mine has started doing this too, same trial and error, not the brakes will try the speedo sensor on my day off.
Very annoying slight whistle that sounds like wind, only does it above 12kph no matter what gear and stops a tad when I lean right.

I've experienced this issue too. What works for me is to ensure the axle nut is not excessively tightened before torquing the pinch bolts + instead of compressing the forks during installation I used the wheel spin-brake method of squaring the axle ala Race-Tech (Fork Installation).

When servicing I thoroughly cleaned the old lube from the seal on the sensor (including the sand trapped in the groove of the seal), used a thin layer of silicone grease, and reassembled.

I sometimes notice the noise reappears after a thorough washing.

 

Ahh ok yeah well i did just wash it...
Its coming on intermittently now

 

I get the same noise, no one is crazy. Mine seems to come and go after the bike gets dusty. I wash it and it goes away for the most part. I've looked the bike over to make sure it's safe and just kept cruising it. I'm probably 6 or 7k miles into the intermittent noise and it's still the same. Doesn't bother me much having driven heavily modified crappy Jeeps the last 7 years that make all kinds of noises.

 

4 year old thread & has anyone figure it out yet? My 2014 with 5500 miles just started doing this after I installed a new tire (Shinko 705). Sounds like a tea kettle. I greased the axle & spedo wheel too, that's it.
Edit: I took the front end apart & wiped all the grease off everywhere & reassembled it bone dry. Loosened the axle nut to around 50 ft/lb. Also adjusted the plastics around the fuel tank & seat (someone claimed that's what it was). The noise went away for the 5 minute ride. Will update if noise comes back. Hope this helps others.

 

 

pads may lightly rub even when brake is released.

 

My 09 is making that annoying noise also, i just had the forks rebuilt and new bearings and greased everything including the speed sensor and torqued everything and still have the sound! Has anyone figured anything out?

 

Stop when out riding. give your front caliper a couple light kicks with your toe, to push the pucks back in a bit, that will make sure there is no pressure on the pads, but be warned it will make the brake lever pull in possibly to the bars when you first brake. You will need to pump the brake back up. Ride and see if the noise is still there. If it has gone away it is your pads chattering on the rotor, you need to clean the slider pin on the carrier and also the pins holding the pads to allow free sliding movement for both the caliper on the carrier and the pads on the pins.

One other thought, has anything been bolted on the front end, a bag or shield or any other change?
