Woah guys. Talk about a hostile attitude - Fadedude was only asking for a bit of advice, and there were some really immature responses. I'd hate to think how your attitudes transcend to your riding behaviour.
Anyway, back to the case in point.. Fadedude, it's difficult to diagnose, as has been mentioned by others. The reason for the 'drifting' could be due to a multitude of factors, such as tire pressures, rider weight, tyre design/manufacturer, past owner suspension tuning etc etc.
What may be worthwhile is checking the RR's suspension settings, to see if they were modified by the previous 'asian owner.' The owners manual should be able to tell you how to reset the suspension the factory settings, and you can go from there.
As for not wanting to adjust the suspension, you should definately experiment with them, but bear in mind that if you make an adjustment to say, the preload, you generally have to adjust the compression too, to really feel the difference. Just play with it, find out what works for you / your wife.
Most of all, hope she enjoys the RR.
Nice track pics, by the way.

Pegscraper, you totally just repeated one of my (less sarcastic) replies 
To add to scraper wrote about making adjustments, don't make real big changes at once...I would set it to the factory settings first (write them down) than make some minor changes (write them down) and so on...that way you can always put it back to stock if the adjustments don't work out.
Here's a good quote I found about lowering the front end by the formula 40 champion from Hi-Side racing:
"How the front is setup is a function of what you have done to the whole bike as far as suspension...
Mine is lowered 5 mm in the front and it handles like its on rails. I don't have to fight it at all.
Here's the thing... why did you lower the front in the first place ?
You lower the front to get it to steer quicker. If you go too far it will feel like it wants to tuck all the time. You raise the rear to get it to finish a corner or hold a tighter line. If you go too far, you spin and the back wants to come around on you. These 2 also work together, i.e if you're too far up in the back when you lower the front, you will have too little trail. Bike will handle like complete crap and you have to start all over.
And of course preload and ride height have different effects. You're adjusting for 2 very different problems when you're adjusting preload and front end ride height.
Preload is to adjust how the bike will ride mid-corner after everything settles out. If you don't have enough spring or preload then yes the front end will ride lower and compound the effects of the lowered front end... you can get around this somewhat by getting on the throttle sooner and pushing the suspension back into the middle of the range.
Just understand that lowering the front in and of itself does not give you the results you are having."

fade...how much do you weigh?
if you're super huge...and the suspension can't account for it based on the existing spring rate, no matter how much you adjust the stocker, you're going to go wide, when you're coming out of the turn. i'm not sure of the RR but other bikes, like the f4i, are undersprung for most riders...
what tires you running on the kawi? what tires you running on the RR when you rode it?
set the suspension up for your weight and it should corner like rails...unless the spring rate is just way too little to begin with.

For those that might be interested.
I somehow came across this thread again somehow, and thought I would tell you guys that actually were interested in my problem, what the problem might be.
She has dunlop sportmax tyres, I checked their website, it seems as if they are supposedly racing tyres, so I though all was good. But now the other day, they had a track day here at phakisa where dunlop was one of the main sponsors. They let them sportmax tyres go for pretty cheap and almost everybody bought a pair to take around the track. ALL of the guys complained of their bikes drifting wide. The dunlop guy just told them that their suspension isn;t set up right! wtf, so now everybody in the world must change their suspension settings (which works fine with other tyres) to accomodate a dunlop tyre? Me not think so...
Anyways I am running pilot powers, happy with them.... would of put them on her bike to but she has decided to sell. So I will never know.
So this was just a little info for those interested.

So you do or don't now realize that tire compound/maker/profile/etc. is all part of the suspension set up equation and greatly affect how a sport bike will handle...like many things on a sport bike...you can't just change one thing as you now know is true with tires (unless you think the Dunlop guy is FOS).
Why do you think so much has to be adjusted for tires in MotoGP (and others), except those guys are actually at the level where they can blame the tires for a mess up...

Tahoe, It just says sportmax...... I checked on dunlop's site and couldn't find the specific tyre that she has, cause as you stated, dunlop has sportmax gp's and qualifiers etc. Hers just plain says.. sportmax. So it might be that they are old also.
Fretless , it seems as if you want to defend dunlop, which is cool, its still just extremely funny that alll the guys that do propper lap times, sub 2 minutes on phakisa, all had exactly the same problem with the dunlops. I don;t know which ones they used, but they were all battling through the turns. They normally ride on pilots or metzlers or perelli's and never has the same destinct problem with any of those tyres. Yes they might say that this tyre is better here and worse there than this other tyre etc etc... but as I said, there was a destinct feeling about the dunlops drifting wide.

My good buddy just got a zx6, personally I think they are extremely ugly. The ass end looks like a tank and the fairings stink. Enjoy your sick bike!
And that has absolutely nothing to do with it's ability to be a kick as track bike now does it. You'd think you'd know there's more to turning than the look of the fairings.

WOW... wish I woulda came on to this thread earlier... I think this is the nastiest ive ever seen these guys get on this forum, sorry bout that fadedude hahahah
I was going to chime in about how I think your kawi has steeper geometry... and I know for a fact a smaller front tire. This would lead to quicker/easier turn ins, but stability starts to degrade. Whereas the 03 600rr is prolly one of the most stable bikes, but that of course, makes it harder to turn in, and perhaps that coupled with the larger front tire would make the rr drift wide with the same input/technique as used on your kawi. Either way, looks like your getting rid of it, bummer. if you need some settings in the future, i think its motorcyclistonline.com has a bunch of "race tested" settings to get you started.
and hey, I LIKE the twitchy throttle on my RR  hahahah and uh... my bro has an 05 636 and with my bike geared -1+3 he couldnt catch me in a straight line till past 3rd gear, then he pulled on me. Its all in what you like, they are all good bikes.

I switched a few years ago from Dunlop to Michelin, but what you wrote about all these "proper lap time guys" hints that they switched tires and didn't have their suspensions set up after the switch...the tire does make a difference...that's all I'm saying...now 
Michelins come to more of a point and this may explain why you get a quicker turn in sensation, because the bike almost falls into the turn...that was the biggest thing I noticed after I switched brands...it almost scared me at first...but I liked it!
