Well .. If you're under warranty, i'd recomend a dealer, just go in, speak to some of the service guys, see if you get a good vibe from them !
If you're not in warranty, definetely deal with Z1 Cycletech in Richmondhill/Thornhill.
You can speak with Glenn, he's a very stand up guy and is always in it to help you out ! HIs mechanics are top notch too, I took a tour of the shop, they keep that place looking good as new ! Very clean shop !
Depends on where you are in the city.
Ken ( Kneedragger88 ) is out in Bowmanville and is a great guy to deal with.
Very honest, very reliable and will take great care of your bike!
If you're in the west end, then PM Johnny ( JohnnyP636 ) and he will hook you up!
Anything you want done, great prices, awesome services and he knows damn well what he's doing.
He can work on the bike while you watch and will take his time to explain things thoroughly so that you're aware of what's going on.
Here's a thread with a lot of pictures of some work he did on my bike...

I'm coming from Vaughan so Ken is too far for me, where is Johnny located? Johnny looks like he would rather do repairs and mods, I feel like I would waste his time just for a simple servicing.
He's out in Mississauga, around the 403/Eglinton area.
I'm sure he wouldn't mind.
What work are you looking to get done anyway?
In all honesty, you should learn to do your own oil changes at the very least.
Download the service manual here, it's for a 750 but the 600 will be the same.
I would personally check/change the air filter, spark plugs and drain all the fluids and refresh.
He can install your new chain/sprockets, he wouldn't mind.
Are you keeping the stock gearing?
This will explain things much better than I could.

I changed my gearing to -1 tooth in the front sprocket to +2 teeth in the rear sprocket and it's by far the best mod I have ever done to my bike.
