Is this only the GS? I don't hear anything like this on the R. I'm afraid I might all of a sudden hear it and then I won't be able to unhear it ;)

Finally.....somebody else with the same problem.
Have you ever had anyone take a look at it to see where it's coming from? A BMW dealer or other mechanic? It's impossible for me to get to a dealer from my location so before I start stripping the bike down I'd appreciate some feedback.
My bike will be recalled soon, and I will go check it out when I stopped by the dealer. The dealer is 1hr ride away, and the stability of 310 is not very good to me, so I think I will wait unitl Oct.

Today, while I was out riding, I revved the engine to around 5700rpm when the noise is at it's loudest and (when it was safe) lowered my head towards the instrument panel. The noise is DEFINITELY coming from the front of the engine up through the gap around the steering head. It's easy to assume it may be from the instrument panel itself (there is another thread on this site with the same noise complaint), but I'm SURE its from the front of the engine i.e. from the airbox/filter region.
I lowered my head to the SIDE of the tank and the noise reduced considerably, hence my reasoning about the airbox/filter area.
I see no alternative but to start taking everything apart and firstly making sure it is all put together properly, and secondly adding sound deadening pads on whatever plastic parts I think could possibly be resonating!
The tank cover is a very large moulding in itself so I think adding some kind of sound-absorbent pads to this would help.
Any other thoughts?????

Hi everyone, I just took ownership of the 310 on last christmas, the bike is at my local dealership after just 30km and the engineers there told me he have swapped the airbox already, throttle body, double check your valves clearance, ignition timing, reset adaptation value yet the roar at 5000-7000rpm is still there. It is uncomfortable to ride with that roar .. I hope to learn more about this issue to resolve this annoying sound

If our bike had the motor in the frame like most, Exhaust in front, intake in rear, We wouldn't hear the intake noise. It's not that this motor makes excessive intake noise, but it's the placement of the intake and a the sound resonates up through the fairing and right in your face.
But the good thing you have to remember is........LOUD INTAKES, SAVE LIVES. LOL

If the sound exist in other bikes, I can accept it but in my case it happens to a few. As an engineer, the loud tok tok tok sound is from a malfunction and may caused the engine to crack or valves to break or cylinder head to break. Do you want to accept this flaw on your new bike?

I was addressing the topic "Annoying air intake noise", only. Not aware there was another noise problem.
Since we have not found the root cause of the sound, we can only suspect either the air intake or the valves. I will keep you posted on the progress. My 310 is still at the dealership
