Humming noise at midrange speeds
08/03/17 at 19:37:11
2011 s40 3300 miles. Never noticed any unsusal noises while riding until tonight. Riding two up with wife, when I got to between 40 and 50 mph a loud whirring or humming noise started to develop. Non existent at lower speed and seemed to go away at higher speed. While noise is present, it did seem to respond to throttle position, i.e. at midrange throttle it seemed the loudest. Any ideas? I was thinking belt at first, but I don't understand how that would only happen at that speed. Throttle or carb I would think would cause the noise at any speed as long as the throttle is in the right place. So I'm lost! Thanks in advance for the help everyone

check the easy things 1st, speedo, headlight, any part on the bike that can come loose. just put your hand on it and if it goes away then you know what to fix.

As Verslagen said.....the headlight trim ring and speedo can make a lot of noise. I thought my cam/rockers were coming apart....turned out to be my headlight. A full face helmet can collect and amplify those sounds.
Also uneven tire wear can make those kind of sounds - check your air pressure and see if the sound only happens when you ride double.

You mentioned that the noise occurred while riding two up. Is it present while riding solo? If not, I would suspect the belt drive, the muffler connection or possibly something rubbing on the tire.

I haven't ridden again since last night. I'll ride solo in the morning and see if it went away. Maybe it was some tire rub.

If it's not still noisy hit the same road and see if it's the road.

My bike has almost the same problem. A sort of hollow whine that starts at 40, peaks at 45, stops at 50.
I have not been able to trace it yet:
I've even coasted downhill with the engine off, also disconnected the speedo. Changed the tire pressures. Adjusted the belt all over the spectrum. Nothing changes it. I am fearful that it is the output shaft bearings or gear whine. :'(

Yes! That describes it perfect. Definitely not the road. I ride same roads all the time.

Belt teeth have to engage the pulley, loose or tight,

If it is gear noise....don't worry about it. There really are very few problems that come from the gear box and transmission on this bike.
The gears can make a bit of a whine at certain speeds and throttle settings - it is nothing to worry about as long as it doesn't get louder as the miles rack up.

If you're not using Rotella T, now is a good time to start.

Yeah, mine whines a ton on deceleration. It's been doing that since I picked it up with low miles so I assumed (actually hoped) that it was normal. I've put more than 4k problem free miles on it since I've owned it.

My bought-new S40 has that same deceleration whine. Since it's my first belt drive, I thought it might be that, but someone on the forum likened it to the whine of a military Jeep tranny. Sure 'nuff, the belt adjustment was fine & running in center of sprockets...and just got used to the whine as "pleasantly quirkie."
