F4I fork how to and where is?

So I swapped in a 2003 F4I fork and brakes onto my viffer.

What does that little screw at the bottom of the forks adjust? What does the tiny little screw on the top adjust and I assume the 7 grooved 14mm rods sticking out the top is preload?

Thanks for the help!

Yes, you adjust the preload with a 14mm wrench, and those grooves help you know where you're at and keep both fork legs at the same level.
The adjustment screw on top of the fork is for rebound damping adjustment, and the screw on the bottom of the fork leg is for compression damping adjustment.

Is this a straight swap or does it require other modifications? Do tell, there's lots of guys over here in Oz that are doing the RC51 mod at the moment, but I haven't seen too much of the F4i forks.

My Viffer is a 2004 model. Have to get the F4i fork, front brakes and both masters. Swap the fork tubes. Rip out all the LBS. Use the viffer axle, wheel with rotors and fender on the F4i fork.

Right now I am using the long one of the stock rear brake lines running to the stock master cylinder. I hear that linking all the pistons in the rear caliper in addition to using the F4i rear master is the thing to do.
