Does anyone know if it is possible to get the front rotor turned? Mine has a bit of a warp to it. No visual defects in it. But surges pretty hard under front braking. |

It is unlikely the rotor is warped. What usually happens is brake dust and other crud build up in the mounting hardware causing the disk to be off center. Thoroughly cleaning the mounting hardware or replacing it can cure that. The other cause is deposits on the surface of the rotor, which is usually due to holding the front brake right after stopping hard. The rotor can also be cleaned to remove the deposits, and using the rear brake to hold the bike at stoplights will prevent that from happening again. |

More then likely it's brake deposits on your rotor you can clean them up I bead blasted mine no more surge.Some have used sand paper on them and that has worked so try cleaning them up first

You can pop it off and see if it's straight. Mine was far from it. |

Get a brake hone to resurface it Won't fix a warp, but will fix deposits http://www.flexhoneblog.com/2012/01/flexible-honin g-for-motorcycle-brake.html |

Get some good HH pads installed, get the rotor wamr, do a few hard stops and they will wipe the deposits right off! Scotch brite pads and some WD-40 works for cleaning the rotor as well. Could be a good time to upgrade to a more efficient rotor like Braking or Galfer. The Galfer can probably be bought for around $215. |

Thanks for the information yall. Just picked the bike up a few days ago wanting to make it right before riding it to much. |

What they said.....many moons ago I took my R in under warranty because I had pulsing at the lever, probably like you are experiencing. The tech cleaned it with something and it was perfect after that. I think soft braking is the reason for buildup. That's my guess anyway. |

Composite brake pads and holding the brakes when stopped at a light are the two main causes. |

Here's a how-to from Stoptech for removing deposits from rotors. http://www.stoptech.com/technical-support/technica l-white-papers/uneven-pad-deposit-removal As Terrys1980 mentioned, some grippier, more-abrasive pads using an HH compound will do a better job of removing deposits. In addition, grippier pads will typically be less-prone to leaving deposits on the rotor in the first place. I'm a big fan of the Dunlopad (DP Brakes) pads, part number SDP993. |

I'll swear by the brake hone #1 - designed for the job #2 - super simple to use #3 - I've used it for over a year now, great results each and every time |

Get out to a race track and you'll have those deposits scrubbed off in a lap or two! |

I have had very good results on several XB/1125 fronts by whacking the rotor at each mount boss lightly with a dead-blow or nylon mallet. Takes 30 seconds. Then re-bed the brakes, several hard stops from 70+mph. Z |
