How do you change the rear shock on a Yamaha Raptor 660?

First remove the compression from the shock by either propping up the rear of the bike or lifting up the rear of the bike. I tied the rear grab bar behind the seat to the ceiling. You will need to remove any skid plate for the swing arm as the shock assembly needs to go downward. You will also need to remove the muffler to allow sufficient room to remove the upper shock mount bolt . Loosen the bolts at the top of the shock with a 19mm wrench and socket. Do the same for the lower bolt using a pair of 17mm metric wrenches. Now remove the bolt that holds the shock linkage to the swing arm with a 17 millimeter wrench and socket. This will allow the shock and linkage to drop down Word through the swing arm. If the shock and linkage do not drops down, adjust the height of the seat relative to the swing arm until it can drop through. Remove the upper bold holding the shock to the frame . You will need to push and wiggle the exhaust pipe out of the way to get the bolt out. This will only work if you previously removed the muffler.Now I remove the bolt that holds the bottom of the shock to the linkage. Now you should be able to remove the shock from the bike. The top and bottom of the shock have spacers that must be retained and reused. Now simply reverse the process to install the new shock. Good Luck. The Gremlin.
