This is one way....

I used a rotor hone in a drill and used low rpms to scuff them up. I took my wheel off and put it in a jig so that they were horizontal. Brian is a vertical kind of guy, though, and likes to see things spin. After I did the outsides, I removed the rotors from the wheel and did the inside surface. I just remounted to the wheel with a couple of bolts. After both sides were done I put the wheel back on the bike and did a test ride. I would say it's 75/80% better. I still have some shuddering but definitely not as bad as before. I don't feel pulsing in the lever so I don't think it's a warp (these are EBC rotors BTW). I'm not all together sure that the pads didn't get out of whack either so today I'm going to scuff them a bit and see what happens.
Well, there's something screwy going on then. At low speed the bike stops normally...no shudder. Stopping from higher speeds, longer time on the front brake, I hear/feel all sorts of pad noise like its slapping them around. I did notice the last time I inspected them the pins were grooved. Don't know if that's causing anything either. Maybe the pads got shot during the first overheating (self induced) session and caused them to go bonkers.... Don't know, but something ain't right.
I am getting mine replaced through my local dealer since Kawi approved the warranty work. I have never had more than just a hint of pulsing but it will be nice to know that the rotors are brand new and have fresh EBC pads.
if you were to stay with oem pads you probably wont warp them again.
I really don't want them to be warped as they're EBCs. And if they do it as well, I think I'm going to cry a bit.
Yeah, I hear that Jim. Still, even if they are EBC and the warranty is up (or there never was one for warpage), it is always worth giving them a call and explaining your disappointment. They may replace them outright or give you a substantial discount on a new set.
But I would still lean toward the cleaning aspect. I have been surprised by it myself and had my rotors pulse after what I thought was more than sufficiently aggressive cleaning only to clean them again more aggressively and have them behave like glass.

Mine started pulsing very badly after I had to brake "very hard" on a down hill stretch......I blew by 3 very slow cages and 1 typical slow Hardly Ableson. I was on the boil and had a pretty good curve coming up, the pulsing lasted for a good while then just seemed to dissapear as quick as it happened. I am going to get some Galfer pads, and I will also keep an eye on my rotors to see if this occurs again.
I just warped up my second set of front rotors, 7400 miles. The dealer just called to say that Kawasaki is replacing the rotors with the new and improved 2011 rotors. There must be a difference that I am not aware of. I asked about the 2010 rotors and pads when my first set warped last year and was told that there was no difference in the rotors for those years. I am just happy to get them fixed without any argument, hopefully this will be the last time.
