I am sure everybody will disagree with me..... But
I wouldnt mess with them. I dont even change my oil or clean my air filter. Just drive it like you stole it and it will be fine.
I have 3500 miles on mine without any problems.... I had the dealer adjust them at 20 hours but I dont think he really did it. He didnt remove my 4 seat cage and I have been told that it cant be done with it on. I just wanted a receipt saying it had been done for my warranty.
I have heard of the valves on the Rhino being a little on the tight side but I have not heard anybody report that they were way off..... Just slightly off. It wouldnt hurt anything.
