Place your GS on its centre stand or in any position so that it has a secure footing.
You are going to need a few tools like a torx bit, paint or similar for marking, pliers maybe, a piece of string maybe and some patience if your fingers are too big. This should take you about 10 minutes or less when you do it for the 5th time.
First thing is to mark the throttle cable adjuster position as you want the play to be the same.
Unscrew the adjuster so you have a bit of play, counting the rotations as you do so.
Unscrew the plastic nut in the throttle cable cover.
Using a torx bit unscrew the screw that holds the rear throttle cable cover in place.

Notice at the bottom of the rear throttle cable cover a catch that is the second anchor point.

This can be a bit fiddlely but you need to lift the cover to the rear and up to free it. Bob's your uncle, Sally your mom and Dick is your best mate.

You now have access to the throttle cable. To get it out, rotate the twist grip and the lug has to slide out towards the twist grip side.

Like so. Now you need to grab the throttle cable or lift it from the track at either of the 2 positions using something to slide in under the cable or pinching it with a needle nose pliers. Please note that there will be tension on the cable at this stage.

Like so but take care not to damage the cable. Hold the cable steady and return the twist grip to its original position to get some play on the cable and slide out the lug towards the twist grip.

Tie a piece of string to the cable to help you thread the cable back through the cover if you feel that it would help when assembling it. Pull the cable out to wards the front of the bike manipulating the assembly as necessary or if the hand guard is in the way undo it to make life easier. The cable is now free to reroute as you wish. Try several options to find a suitable route. Take care that the cable doesn't bind or rub/chafe on any part of the handle bars and rotate the handle bars through the full arc of travel to check for it and also that it doesn't tighten/stretch anywhere.

Assembly is the reverse of the steps above. Thread the string through and pull the cable into the front cover manipulating the cable as you do to prevent it from binding in the front cover. It helps to insert it with the natural curve of the cable facing upwards. If you have chosen not to use a piece of string then the cable can be recovered from the front cover by using your needle nose pliers to pinch the lug and pull it through. When locating the cable make sure that it lies with-in the track to prevent binding in operation of the throttle.

Before fitting the rear throttle cable cover, start the bike and rotate the handle bars through the full arc of travel. If the engine rpm rises then the cable is pulling tight and you need to check the routing again. This is important to check. If all is ok then finish the assembly and take the bike for a ride.
Last note. If the cable is chafing anywhere you need to separate cable from that part. Easy way of doing is to get a piece of self adhesive foam rubber strip and sticking that to the offending part.

Happy days :D

To the mods. I wanted to post this in the font of all wisdom but don't have the privilege to do so. If you feel that this is worth it please feel free to move the post.
 
Nice post and good description & pics, however......

Is it not easier to undo left fork leg from top clamp as follows?
undo left fork slider from top clamp,
lower left fork slider,
re-route throttle cable behind instead of in front of left fork leg,
re-position left fork slider and tighten,
job done,
no pics or torque values available,
total time 5 minutes ;)

Agreed. Much easier. :thumb2
 
Thank you very much. It depends if you need to reroute the throttle cable or brake lines where you are going to undo the forks. I have a 09GSA and the throttle cable is routed originally from behind the LH fork. This way as I have described you can route the cable any way you like. Over/under the handle bar, in front or behind the risers, over/under the hand guards. There are more ways than one to skin a cat.
 
After fitting bar risers (40mm)/ rox risers you may need to reroute the throttle cable.
