I have done some searches on this and it appears someone had the same problem but people said it was clutch or airbox related. I don't think that is correct but I will describe the problem again.

First and foremost, this noise occurs in ALL gears, at different rpm, and only happens at 25%-35% throttle position. It concerns me as it makes me think that something is loose. I'm going to have a mechanic check it out this weekend but if anyone has had this before I'd love to save some dough. Any suggestions?
