To get to the top bolt of the shock you'll need to remove the oil tank from the left side of the bike which is located under the side panel. I also have the gas tank off in this picture which is recommended, but you may be able to get the oil tank out with it in place. You'll need to either drain the tank, or quickly remove the oil line connection and plug the hole with something once the tank is free. Also disconnect the oil tank sender unit from the electrical harness by disconnecting the 2 prong plug. Now the oil tank can be removed by removing the two bolts shown above.
With the tank removed you can clearly see the nut end of the upper shock bolt.
Remove the battery from beneath the right hand side panel cover and you'll see the top shock bolt. Remove this bolt and the nut on the oil tank side and the shock should drop out from the bottom of the bike.
There is an adjuster wheel and belt which will be left in the bike. You can remove it by removing the air box, or just cut the belt off and leave it in place. It won't be used after the new shock is in place.
