Yeah my 1000 was ridden really hard. Bike rotors are full floating rotors. It's not like a car rotor unless it's a supercar. The rotors on my 1000 were so loose on the buttons and making noise when I replaced them.

If it's shaking and your not braking really hard then my guess is going to be a warped rotor or bent wheel.

Just get a magnetic dial indicator from Harbor Freight for a few bucks. You can use it to check wheels, rotors, forks, etc. Its a good investment because you'll probably need it in the future for something. It'll save you money from buying replacement parts for things that you "think" are bent but aren't sure. Attach it to the bike or stand, line it up on the rotor and spin the wheel.

Here is a vid checking the wheel. Same process for rotors.

Of course that was the first thing I thought, easy enough to check out. Put it on the stands and spin the tire. Then I tried scrubbing the rotors, then I tried new brake pads. I checked the steering head bearings, all that.
Then somebody suggested the packing/fork adjustment idea.
Twiddled the knobs, carefully of course, and TA DA! it was fixed. (don't do this if you are not familiar with what you are doing. You can make things much worse)

To the OP....
Take it to Patrick at Motorcycles Unlimited first. He told you he would check it out no charge. Don't throw money at it until you know what's wrong.


or not.
I'm gonna go ahead and take it to him. Its been stunted hard and I've dropped it a few times myself.

I'm a millwright so I have plenty of the high dollar starrett dial indicators. Never even thought of that. Good looking out!!

One more thing to add: when you have a warped rotor, or at least in my case, your brake lever will be really firm at a stand still but when it gets rolling the warped rotor will work the pads back into the caliper slightly and will make the lever pull much greater. Kind of hard to explain, but i had to pump once or twice to get a firm handle every time i had to stop
