Hey guys, I was hoping to get a few pics of where and how you mounted your CDI's on the Pvl conversion early model cr250's. New to this forum but it looks great! Thanks in advance. |

Anything in particular you need to see? I did one on a MR250 and I have a few pictures, but it went together pretty easily. |

I was hoping to see how and where the CDI is mounted. I have a couple of different ideas, but i dont want to re-invent the wheel if i dont have to. Thanks! |

The CR250M and MR175 frames are pretty similar under the tank, so this might help with mounting ideas (CR125M ignition in MR175 frame): http://i399.photobucket.com/albums/pp74 ... 1754-1.jpg The coil mount is 1/2" x 3/4" aluminum channel mounted to the front OEM coil-bracket hole and the frame crossbar, using an MR175 skid-plate mounting clamp (P/N 50358-361-000). The CDI uses the rear coil hole and a 1/4" / 6mm hole drilled thru the crossbar. The "before' setup on the left used the new coil mount for grounding which relied on additional bolts and metal-metal contact, so I wired it direct to the frame bracket along with the main wiring-harness ground (these can also be connected together). Once the coil was out of the way there was room for the CDI box, and the plug lead has a smooth arc to the plug without much bending. This setup has been working great for years. Ray |

I could have machined brackets and all sorts of garbage, but I wanted to keep it super simple. I used the coil bracket as my starting point, I threaded a longer than needed bolt through the coil side leaving a stud to attach the CDI (these pictures were just a mock up). I then a collar to space it about an 1/8 of an inch away from the bracket, added a washer, rubber grommet then tightend it down. I checked tank clearence and there is plenty. Buttoned it up and went racing this weekend- performed flawlessly- easier starting and no more points to deal with.
