Ask tigger to find a manual for the bike online. I know hes got a few sites that have them. Either that or find a haynes manual. I have one and its helped out a lot.

For those forks, you will need a fork spring compressor. There's two ways to go about it. This way http://traxxion.com/detail-25.aspx or this way http://traxxion.com/detail-26.aspx

There's a nut at the top of those forks that pretty much holds everything together and you've got to compress the fork spring to get at it.

After you've got the old oil out and the new oil in, you gonna need to set you oil height (the space of air between the top of the fork oil and the top of the fork tube). For that you're gonna something like this http://traxxion.com/detail-42.aspx

To do this seemingly easy job, you're gonna have to take the forks almost completely apart, then reassemble them and then set sag/rebound/compression. I had to have a friend show me how after I bought my RC. I thought it was gonna be easy, I quickly found out that it isn't.

If you have the service manual for your bike, it will have step by step instruction on how to do this.

First thing you need to do is get a service manual. You're gonna need all those words. I know I've seen video of it...probly not as in depth as you want it to be but it should give you a solid idea after you read the manual. Peruse Youtube.

Triple,

I want to buy your memoirs.

Your life would make a great sitcom.

We must act quickly before the blue-collar/redneck comedy phase is over.

As mentioned already if you can get the forks off yourself, you can get them forks rebuilt for a reasonable price. My CR250 forks were $125 for new oil, seals and bushings and I had them done yearly. I always had mine done at Pro Action suspension. I'm sure they can do sport bike forks.

Traxxion Dynamics is less than an hour from my house. They can do a full rebuild on my forks for $150. Is this appropriate for the work involved?

Seems to be on par as far as pricing goes.

Thats why you find out from tigger or someone else who knows where to find the free ones online if there is one for your bike.
