They make strange noises if your not familiar with the rzr. This is my first one and I swear it was at the shop weekly for the first month and ever time the dealer showed me several on the showroom floor that made the same noises. Most of my noises were coming from the clutch when the arms move around and stuff and the belt slapping the housing when I would rev it up. The dealers answer was "well, you're not supposed to rev it up like that in neutral". And then showed me that every single rzr 900 they had did it. I also had the ticking, mainly when it would first start up and that was the cam chain tensioner. And again the dealer said it is normal and showed me a few brand new ones that made the same noise. I ended up changing the tensioner to an automatic mechanical one so that noise is gone. I just got used to the rest now.
