How do I adjust it, I cant find an adjuster, i really need to adjust it, please help.

 

there are to allen head bolts at the end of the swingarm they are silver and about a fist length appart,loosen them so they are almost out.then right next to the rear sprocket there is the adjuster,stick a spanner wrench or a screwdriver or something in one of the slots and pull it back towards you.then tighten up the 2 allen bolts on the swingarm.
