Ted it's a 2012. There's a magnetic run out gauge at work somewhere that I'll try and get my hands on tomorrow and attach it, but I wasn't sure how accurate a reading would be on semi floating disks...

Update: I took the bike to work this morning - 45 mile commute. At freeway speeds the pulsation is severe. Absolutely not rideable. I took it very easy for the commute in both directions and it's parked up. For the immediate future I'm going to take a sanding disk to the old rotors and gently clean them and reinstall them with the now new EBC pads.

Ok, not sure what to say here.
Suggest doing the readings and let us know what you find out.
Think I would check runout on the rim while your doing them.
Hopefully others have some idea where to go next??

Ride safe, Ted

PS: You can buy a inexpensive travel dial and magnet at HF.
      Should be relatively simple to build a mount to attach it to your forks.

If you running the Chinese rotors, did you shim the ABS sensor?  Many of us have had to do this, probably 2 washers- depending on the thickness. When I first installed the rotors, the brake pulsation was downright dangerous!

I had read on here that that might be an issue and my sensor was also going to rub, so it got a shim before riding. Good looking out.

Update:
I wasn't able to get a runout gauge from work but I contacted the company from eBay and explained the situation and they easily agreed to send me out a new set of rotors which suggests that this isn' the first complaint about their rotors being warped form new....anyway, there's a storm in the asian pacific thats holding them up so I decided to take a buffing disk to my original rotors and put put them back on with the new EBC pads.
       And now there's no pulsation - surprise surprise I hear you say. Stops very smoothly. I just didn't want to b dealing with a routine disk sanding but because it was factory pads that were supposedly leaving deposits on the rotors that shouldn't be an issue with new pads.

 Long story short, I should have saved myself $150 and removed the rotors, give them a good blast with the sanding disk and replaced the factory pads. I figured I didn't want to be sanding regularly, and I wasn't convinced the pads were leaving deposits.

Anyway, I'm off to put some salt on my hat and eat it. Appreciate all the good info on here.

Glad it worked out for you.

Takes a big man to admit he was in error.
Saaaalute!!

Ride safe, Ted

No harm, no foul. Glad you got it all working well. Sorry to hear the new rotors didn't work out.

+1 on the EBC's. I got mine from Murph as well. I was not impressed with the OEM's. I looked at the Brake Tech's but decided to save a few bucks with the EBC's. They've been rock solid.

EBC rotors rock - big improvement from stock
