2001 FZS600 - service intervals?

[mr self destruct]

Depends how much dosh you want to spend really?

You're better off getting a Haynes manual and start learning to do the basics yourself though to be honest.
Coolant, plugs and oil are simple enough to do, but maintaining things like brake calipers are certainly worth learning, especially as it is quite an important part of the bike and if you look after them once or twice a year they will serve you well in the long run.

And of course if you need any advice whatsoever you can always ask on here.  :thumbup

Also, there a comprehensive service schedule guide at the front of the manual, which should answer all the OP's questions.
