Need Info on 2010 Rzr 800

Well I’m back in the Po-Po world. Used to own a RZR XP900 and sold her and now I have a 2010 Rzr 800 50". I would like to get some info if someone can help me. I realize that some of the questions can be bias and very subjective but I like to see what everyone is running and do my on research. If I forgot something please add it too the list. Thanks a bunch.

1. CVT belt Number. Polaris number and Gates or any other brand numbers.
2. Spark Plug number, most likely will run NGK unless the Rzr runs on something better.
3. Service Manual
4. Air Filter number
5. Recommended fluids for front-rear-tranny and engine. Is Polaris kit the best to use??? I know this question is very subjective. The guys that don’t use the Polaris Kit please give me weights.
6. What clutching are you using??? Another subjective question…
7. Recommended axles OEM or off brand
8. Best bushings OEM or off brand?
