I have heard that a 520 conversion is something that most should do to a sport bike. What exactly does it do for performace? Also if anyone has the recommended supension settings from the april 600 smackdown for the 05' zx-6r would be appreciated.

I have a 520 chain/sprocket on the SV.
A 520 is a lighter, slightly smaller chain. Less weight, less mass in the drive chain should equate to a very slight increase in performance. Very slight being the operative words.
Unless you need to replace the chain/sprockets (always replace them as a set) right now, I would probably spend money elsewhere
Also, if you neglect your chains, staying with the stock 525 will probably mean longer life but if you do routine maintenance, a 520 can't hurt.

If I remember, the chain saves about three ounces. Hardly worth the expense or trouble.

Not if you're replacing the stock chain/sprockets because of wear. You'll not only save a little weight, but you'll definitely be saving some $$ over just buying the stock OE stuff.
The ZX-6R already comes with a size 525 chain and sprockets, so switching to a size 520 just for the sake of changing may not gain you much.

You can save more than that because you ususlly move to an all AL rear sprocket as opposed to the steel original. And it lowers unsprung weight on the rear end as well which is always appreciated. I would suggest doing that when it comes time to replace the chain. It's short money.

With the Kawasaki ZX-6R's 525 stock OE setup, you won't gain that much, even with an aluminum rear sprocket. The stock steel unit is surprisingly light; it's hollowed out quite a bit.
That said, as I noted before, if it's time to replace the sprocket/chain, I see no reason not to go with the smaller and lighter 520. There are also sprockets coming out that are composite construction; an aluminum inner section fastened to a steel outer ring, giving the wear of a steel unit with the light weight of an aluminum one.

Ok I am actually asking about the conversion for a 04' R1 which I ride. I am asking for the supension specs on the 6R for a friend. The stock R1 has a 530 OE chain. So will a 520 do me any good?

On a bike with that much output, I think it'll go through 520 chains fairly quickly. Definitely get a rivet-type master link and not the clip-type master link on an R1.
Just my 2-cents.

Switching from a 530 to a 520 setup will save you about 2 lbs., and probably free up a little horsepower. However, you will be going through chains/sprockets more frequently than with the stock OE 530 setup, especially if you're hard on equipment and don't keep up with normal maintanence.
Today's name brand 520 o-ring chains are actually quite strong, and can easily handle the power of a literbike. But you will need to keep up on proper adjustment and maintenance for best results.

I wouldn't do it on a liter bike period, end of story.
The extra torque will tear up an aluminum rear in no time.
