I would get the manual, they are like 20.00. that's the first thing I do when I buy a four wheeler. Change all fluids, change the plug, The rear brakes can be adjusted from the rear master cylinder, behind your right leg is where it should be. Unscrew the bolt and then turn the long shaft which ever way you need to go.
If you had a manual you would know what the hell I was talking about.LOL
any questions email me I can alway scan some pages out of mine and send to you.
