thanks a millionRaptorRandy27 said:It's very simple, you loosen the 4 pinch bolts at the back of the swingarm and then on the left side of the bearing carrier the is a round hole you can put a phillips screw driver in and then the spocket hub will contact the shaft of the screw driver. Then roll the quad back and it moves the carrier that is eccentric and loosens the chain if you get it to loose push it forward and it will tighten back up. Allow your self about 1'' of deflection measured at the front chain slider so your suspension doesn't bind thru the range of travel. Don't forget to tighten the pinch bolts back up. Recheck your chain for slack after tightening the pinch bolts back up. You can also see this illustrated in your owners manual.
