Pro xs engine noise

I have a new 09 Puma with a 250 Pro XS and was wondering what could be causing a loose washer or bolt noise at around 3000 to 3500 rpm coming from inside the cowl or outside the engine? I know that there is a harmonic resonance from the reed slap but it seems to be causing a vibration somewhere. Thanks, Josh

Are you sure it is not a chatter sounding noise. they all do this if so and it is just the reeds chattering I think !! Bass Cat or somebody else will chime in and correct me if I am wrong !! Good Luck

The mid rpm whistle is the air compressor sometimes. The rattle is often the lower motor mount covers rattling and not under the cowl. BCB

Do you have one of the new ladders, I have one on my 08 Cougar FTD and it took me several trips out to figure out what was making that noise. Was very concerned until I realized what it was. Good Luck, JR
