I just purchased a 2011 Razr 900xp. It currently has 116 hours on it. Its basically bone stock. What is the first thing I should do besides change all the fluids? Should I change the belt? add a clutch kit? Are the High Lifter 3GX ATV Drive Belt by Dayco any good? (about $112 for one of those)

Just trying to figure out how to make this machine as reliable as possible…

Thanks in advance !!!!
