Weird howling/whining noise in 3rd gear
Hello everyone! This past week i've been experiencing a noise problem with my 2007 Versys and i'm hoping i can get some help in either resolving the issue or waive it as normal.
The best i can describe this noise is howling/whining like when there's strong winds outside blowing, and you can hear them howling through the cracks. The noise does not happen in 1st and 2nd gear, or at least i cannot hear it, but as soon as shifting into 3rd gear it starts and goes on to the 4th gear and so on. I normally don't ride in the low range but even in third gear if I am below 40km/h for the sake of trying, the noise isn't audible. Almost seems like it would be resonance, but I don't think it is. The noise is better heard while standing straight on the bike and seems to be comming from either front end or directly under the tank (it's not venting).
The bike has 48000 kms on the clock, valve clearences adjusted, fresh oil (motul 7100 10w40), the tires are in good shape, the chain and sprockets are also in good shape, clean and without any play, the chain has the correct slack and is straight. I just changed the front wheel bearings as I thought those might be the culprit, but they were not.
I couldn't reproduce the noise with the back wheel on the stand, which kind of leads me to believe it might be the rear wheel bearings maybe?
The only thing I did on the day this noise started happening was to tidy up some cables on the front of the bike, which also led me to believe there might be extra air going into the air box and resonating, but this is a bit stretched out.
I've tried switching helmets but it's still there. It was easy to notice this noise because it recently started happening, prior to this the bike had no weird noises, no vibration noises, just the clear engine noise.
When cruising and pulling the clutch in, i can still hear the noise but a it's a bit faint.
Other than this, the bike shifts fine, no loss of power or any of the sorts.
I'm trying to get a video on this, but it's hard to get the camera strapped on my leg, even though i did it, it's hard to distinguish it between road noises, chain rollers and engine sound, but I'm still trying.
Any input on this is greatly appreciated. I will try to update this thread as I go on.
