Re: Harmonic noise at low speed
Mine had a similar noise when I first bought it. I was convinced it was coming from the clutches as well. Ended up being my metal roof vibrating when the motor was hitting certain RPMs, it was so damn loud you couldn't really tell where it was coming from.
I was able to get the noise to happen consistently then have someone start pressing and holding their hands on any sheet metal parts until I found it. I would check all your aftermarket parts, put foam between anything made of sheet metal and the frame.
