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.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.
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?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
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 dealershipI was addressing the topic "Annoying air intake noise", only. Not aware there was another noise problem.
Yep.....
they sa K&N adds more air and performance? is this really good for the engine or yes leave as is what it was designed for ?Nope, changing the filter will not make the induction sound go away. The airbox volume and shape(length of snorkel/trumpet) are frequency tuned to the engine. See: https://en.wikipedia.org/wiki/Helmholtz_resonance And yes there are at least to alternative so called free flowing airfilters on the market, KN and BMC, here is the BMC variant: FM993/20 - Replacement Filters Panel | BMC AIRFILTERS I would not waste money on it. Here you can see how to change the filter on a G310 R:
