What radial setup works on the rvf? I am looking at upgrading the brakes for racing.

You need different fork bottoms to run radial brakes? Think Mruehl runs PVM radial brakes on his RVF but he has different forks..
Radial brakes are a fashion fad IMO anyways...

I agree totally - the reason, the REAL reason, they are used on factory racebikes and the likes, are primarily to allow different sized disks to be fitted more easily. The caliper can be spaced far easier than with traditional mounts. A pad in a radially mounted caliper offers absolutely no more stopping power when compared to one of exactly the same surface area mounted conventionally.
No more than bling on anything other than pure race-bikes.

I dont get the point of radial master cylinders either, but maybe im old fashioned, or i dont pretend i can ride as good as rossi or stoner etc

Right!!!
Many of parts on my bike make me not faster. It is nice tro have the parts for the bike. Why people buy a motogp
bike? To put it into the livingroom? Is that fast or nice to have? I like the bike (V4 in small) and i like to built my own bike.
I can´t explain it better in english, sorry.

I think I'm right in saying radial master cylinders have their advantage in providing a 'squarer' angle between the lever and master piston and hence giving a bit more leverage. Oh, and it makes the bars looks slightly less cluttered.

you explained it better in English than I could have tried auf Deutsch!
They are pretty looking things and your bike would not look right without them
In the real world nobody can really tell the difference between the perforamcen of non radial and radial.
You might cast the calipers lighter and the fork bottoms lights and this is the only decent advantage I can see - apart form the swapping disc sizes etc as already mentioned.

radial mastercylinder makes a big difference, calipers make no difference unless you changing disks as already mentioned
if you want a shit hot brake setup get a bembo radial braided lines sp1/cbr600/900 calipers race pads and braking (or similar) disks
cost you the best part of £500 tho new
personally iv got cbr600/900/sp1 calipers braided lines and a cbr600rr master cylinder and the brakes are amazing, no nead to upgrade anymore and some say there almost too good anyway and it all xost me £90 off ebay
the only thing id think about doing to the brakes now would be lighter front disks (less rotating momentum) and racing fluid

Why? Have you anything to support that view?
I know that we need to force fluid down some lines to some calipers - why does it matter how the fluid is pushed? Is it a leverage issue for gerater "feel"?

my rvf race bike has:-
front - standard calippers and m/c, braided lines, pfm cast iron discs and pads to suit
rear - complete standard set up
the front brakes can stand the bike on its nose with ease while giving great feedback.
the rear brake is only used for stability so the oe set-up is fine as is.
as said above, there are few riders that could honestly hold there hand up and say they can tell the difference in raidial - non radial.
