Check your neck bearing. Maybe its loose 
. I had some same problems with my front. Checked everything. Then att last I changed to tappered roll bearings in the neck and some new wheelbearings and the problem wenth away.

Re: Front f4i brake sssssttttttttutter!
I was waiting for this to pop up, if your rotors are straight it could be your front wheel bearing or even steering stem. There are fixed calipers on the front so you cant 'lube' them, you can make sure there is no dirt on the pistons...im not sure so I cant argue the tire possibility....

Re: Front f4i brake sssssttttttttutter!
The pistons on the calipers were terrible!
I had trouble getting some of them to even expand at first without the pads in. I cleaned the hell out of all of them like Extremeacres said.
I also put an angle on the leading edge of the pads too.
It's midnight here so I couldn't really raise hell like I wanted to in the neighborhood but thay are SOOOO much smoother. Not so much of an "on" "off" feel anymore.
I didn't use the 636 master yet.
Thanks so far.
I'll keep posting progress

Re: Front f4i brake sssssttttttttutter!
Stutter seemed like a good word for this 
Don't know whats up with my front brakes. When I practice my endos I have to do like 20 of them before my brakes actually feel smooth enough to roll em out.
It feels like they are grabbing letting go and grabbing again really fast kinda like a ssssstttttutttter!
Maybe it's just that they get smoother as they get hotter
And No the rotors aren't bent or warped.
I've been having trouble with this for a while but it starting to bother the hell outta me. Forget doin a decent endo during a show or comp
I don't know if they're stock or what I've never had any experience with aftermarket pads because I always bought stock in the past for other bikes
Do HH pads do this?
How can I tell what kind I have?

Trash the front end and go 954rr or 600rr.
yeah you can go 1000rr but some ppl still have the same problem.
