The instructions are in the service manual chapter 3 page 10.
Remove the rear wheel, ECU, rectifier/regulator, fuse box 1, starter relay, all hoses and clamps and the drive chain tensioner. I am assuming of course that you have an XTX/R and not a Tenere of course.

I am making a stage 3 myself soon would be interested to see some pictures of yours if you have the time.
