Same for me, I had it happen going down my driveway the other day. I will say the warmer it is the more likely it will happen. Always seems to be under light load i.e. if I take my foot off the gas it goes away, if I throttle heavy it goes away. With a little more warmer weather I will try to isolate this instead of just replacing parts until it goes away. It can be very loud at times too, almost like when blowing on a bottle just right...the type of sound that travels easily. All the reading I've done has shown people getting positive results from replacing and taping different things...almost like taping prevents the air to the flute and in the case of replace parts, like a similar part is used in multiple places.
