Okay,
Just use the spring/rider weight guide in the owners manual.
Which I believe is .46NM's for the forks, or .47KG springs, and a 76NM rear spring or a 7.8KG rear spring. Set the rear static at 33mm to start, and the adjustable for pre load at 4 turns in. That should put him right around 100mm of rider sag, which is about where you want to be.
Set clickers at standard and play around with it from there, but, don't go beyond the rec clicker settings, you'll or rather he'll end up chasing his tail. I found that the "sport" settings only made the ride harsh with the stock valving.
With the correct springs the bike will be night and day difference for him.
Hope this helps.
