Just wanted to see if there is anyone else out there besides Twin Motorcycles in the Netherlands that does the Rotor Oil Jet Mod on my 2009 1125CR correctly... They say turn around time is 6 weeks! Loaner tools for this? I will gladly pay a refundable deposit minus shipping charges. |

There are threads floating around for DIY with a machine shop doing the EDM and also threads for loaner tools. Google is your friend. No one in the US does rotor mods specifically for Buells. You can always purchase a EBR modified rotor from Liquid Asset Partners. Y0533.13AZ See this post. http://www.badweatherbikers.com/cgibin/discus/show.cgi?290431/778104 (Message edited by terrys1980 on February 12, 2016) |

I realize that this may be redundant, however,... Y0533.13AZ is the MODIFIED rotor and it will fit the 2009 1125r or cr. Is this correct? |

I got mine done at a local EDM shop during lunch time. This hole is not a super technical process. EDM is used because drill bits this small are painful. I don't really want to go into business but I could help out fellow Buellers until EBR gets back on their feet. I work in the automotive industry and manage folks that design paint applicators. The fluid dynamics of this oil hole and the way paint is atomized is very similar. I used knowledge of bell cups to optimize the angle of the hole. Pictures of my rotor are on the air cooled rotor thread. PM me if you would like to discuss getting your rotor done. |

I had my rotor drilled at a local machine shop. Quite technically, it's a .040" hole drilled at a 45 degree angle from the radius of the rotor (the curved portion as it turns up to the splined hub), into the keyed channel which serves as the main oil passageway. I would be more than happy to employ my local machinist with more of these if anyone wants to send them to me. However, if you take what I just told you and have a local guy do the work. Most competent machinists would know what you're telling them. I've put 6k miles on my new system and its not failed once. the original system failed before 2k miles on the new bike.

Chris, I believe the EBR rotor mod creates a .78mm hole which equates to .030". This from memory when I did mine I measured the hole with a drill bit. Can anyone definitively confirm or refute this? |

.030" that's what mine is drilled out to. That's a # 68 drill bit EBR called for a #70 bit its a little bigger. Its been all good for the last 40,000 miles. |

I came up with .028" IIRC |

just to clarify, is the drilled hole the only difference between the stock rotor and the rotor you would receive from Twin cycles or st pauls harley? If so - i'll probably look to have a local fab shop in Adelaide do this (with some of your lovely guidance). |

We used an EBR rotor to check the sizing and the angle. Our machinist said the hole on the one we looked at are around .020 and the only way is to use and EDM machine then machine the inside to capacitor the oil passage on the crank shaft. We paid to have a jig made to hold the rotors at the proper angle to complete the job correctly on both the EDM and the CNC machine. |
