While looking over my 1998 S1 White Lightning I noticed the front brake rotor was loose. It appears as though the pins which hold it in place are warn. however I am afraid it may be the three spoked piece it ataches to as it is aluminum.I am worried the rotor may come off in operation! Is this play normal, and if not, shouldn't the pins be wearing out not the flange?

Those rotors are known for this problem.
The best thing to do is replace it with a new style Buell rotor or one of the aftermarket units.
The Buell rotors are not cheap, neither are the aftermarket units.
Ping one of the sponsor dealers on this site for a price.
Al at American Sport Bike can get you numbers on a couple of different aftermarket units.

Like Brad said, common, and not fixable. You need a new rotor. Used to be OEM 2000 spec was the way to go, but it's too expensive now. I personally would put the ferodo on it, here: http://www.americansportbike.com/shoponline/ccp0-p rodshow/6056.html

Getting the screws out is an adventure. A brass drift and heat are your friends, but there's a good chance that you'll be welding some nuts to the top of the bolts to get the flat head bolts out.

Thanks Guys! Sounds like fun. Until then, about how much play would you feel comfortable riding with? I've got about a sixteenth of an inch, may be a hair more.

I don't think anyone could say what the right number is there... I know when mine went, I wasn't looking at the amount of travel, it was the volume of the chatter!

But it's your front brake. If you lose it, you die. Don't let it go too far.

In addition to the brass drift and heat, you might also try some PB Blaster. That stuff is pretty good penetrating fluid. Better than WD-40, me thinks.

When I did it I started easy. But I ended up going to judicious amounts of heat, a steel chisel, and a big hammer. Though the star and bolts were trashed the rim was fine. Them things are really in there.

The other alternitave is to replace the aluminum center carrier. that is what wears out and oblongs the holes. You can get a 'kit' from HD for about $148.00 and get an extra packet of wave washers so as to be able to run two washers on each floater bolt. I just did it, perfect results and simple.

Replacing the aluminum carrier with another 6 button unit just guarantees you'll have the same problem again in 10,000 miles or so. 6 buttons just don't have enough area to distribute the load over, which is why Buell and the aftermarket units all use 9 buttons now. If it was a $50 fix, it might be worth it. But at $150, it doesn't pay to go that way, IMHO.
