Hi Pigford.
I have not noticed any "fluttering" noise in my 2005 TT600RE. The intake is stock, the snorkel is in the airbox and it has the stock airfilter. I am 99% sure the stock exhaust has been opened up a little so it probably is a little louder and may drown out other noises.
Could the engine be sucking air somewhere it shouldn’t?
I however hear a little extra noise right after I start the engine, right before the oil pressure builds.
