Brett, if you go by what it says in the handbook and service guide then you won't go far wrong.

If you take a glance at this item in the FAQ section it will give you an insight to servicing a TTR.

That's a good guide Martyn.

Someone asked recently whether you can change the fork oil without totally dismantling the forks. It seems you can

I did change the fork oil. Something I regularly do on bikes I get. An oft
overlooked aspect of preventative maintenance. It's oil and it gets worn out.
New oil makes the bike feel plush again keeps all the fork repair jobs at bay.
I've found that Silkolene Factory Light is as close to the Yamaha 01 fluid, or
whatever it is, that the book says. You don't have to take the forks fully apart
but you will need to take the tops off and you will need to separate the plunger
from the tops to do a proper measured refill and getting the plungers
re-attached to the fork tops can be tricky. I used a bit of gardening wire. Turn
them upside down and drain them. Work the plungers and make sure (nearly) all
the fluid is out and leave them like that for a bit. Fill up as per the book and
refit.
