Its the routing that proves to be the trickiest, especially making sure you dont wrap the cables (or they dont wrap themselves) around each other. You may want to do some recon work and inspect where the cables loop under the headlight and transition into the engine bay. Patience, attention to detail and pictures will be your friend.
I found that one of my cables appeared to be a bit too short, however there is a mod online somewhere where they bend one of the cable stops a little forward at the throttle body. I was able to get mine to work without doing that by fully "loosening" the cable adjuster, and the throttle cables are smooth and free, regardless of position.
I didn't consult the manual, but followed the instructions that came with the kit. This seems to be one of those jobs that is much easier done the 2nd time. LOL.
Let me know if you run into a head scratcher and we'll figure it out.
Here is one of the trickier parts. This is right under the steering head.

Here is also something I found helpful to doing the throttle cables (from badweb)
-The two on the left are for the throttle return and throttle open. One with the black nuts is throttle return and goes on the bottom U of the silver cable bracket.
The silver nutted cable is the throttle open and it goes in the top U of the bracket.
Attach the throttle body side of the cable FIRST or you'll have a hell of a time having enough slack... leave the handlebar ends loose.
Black nut cable (throttle return) goes along the bottom of the throttle body barrel (black plastic thing with groove it in attached to spring) and attaches to the rear-most hole--you're going to have to open the throttle bodies to access it.
Silver nut cable (throttle open) goes along top of the throttle body barrel and attaches to the forward-most hole.
Then do the handlebar side of the cables.
