Funny you should ask. I just did mine last week.
I sent this to gasgas-HI and it worked for him.
1) remove pipe and silencer
2) remove rear wheel
3) remove bolt for suspension linkage dog bone at swing arm only.Pivot down.
4)remove both shock mounting bolts.
5) raise swing arm up all the way.
6) lower shock to the left side of the suspension bell crank, enough for the shock to clear the upper frame mount.
7) pull the shock out on the right side of bike.
