On my 900SS SP there was a little diagram on the swing arm that gave the chain adjustment parameters. It also specified 25mm. That was the distance the chain was to travel from being pushed as CLOSE to the swing arm as possible to as FAR as possible from the swing arm. That distance should be 25mm. measure at the approximate of the swingarm.
Just remember that a new chain will stretch, so no matter what you do, keep an eye on the chain tension regularly for at least the brek-in period.
'Hope this helps.
Once you try track, you never go back.
