Hi Fish

Have tried a couple of times to put an anwer on your post but won't let me so thought would post a seperate reply.

My 2007 manual advised change  fork oil at 80,000 km.

Its not a real hard job to do, so if you could probally do if U wanted.

I have some Heavy Duty SE fork oil to put in mine but am just waiting to do when I pull my forks off to get them Chromed. Iam also considering changing the Springs to a Heavy wind as well. 

Hope this helps
