Hi folks. I am finishing my recent restoration of a 75 cr125 that I picked up cheap. The bike came with no exhaust pipe so I bought an original off Ebay with some dents. I am trying to decide what route to go with this. I am aiming for "like new condition". Here are the options I am looking at: send my pipe to Motocrosspiperepair.com, anyone have any experience with them? Buy an aftermarket DG pipe like this one http://dirtoverstock.com/detail.aspx?ID=140 The thing that I need help with is , I want the pipe to follow the stock positioning and contour, I have seen some aftermarket pipes that look too low out near the end. They follow along or below the swingarm , the originals were more upswept and terminated by the shock. If anyone has the DG pipe could you please verify that it follows the stock looking positioning on the bike. Pictures of the DG pipe on your bike would be great as well. Or any link to some other aftermarket pipe that looks correct. Thanks very much Mark |

Mark, There's also Pacific Crest Pipe Repair (http://www.piperepair.com) - the feedback I've read has been overwhelmingly positive about them. I recently used JB Weld to fill in a small dent in the headpipe plus five stamped-in recesses where heat-shield mounts had been on my MR175 pipe; it worked great. A few days ago the headpipe repair took a direct hit from a big branch while smoking hot, and all that happened was the paint scraped off the JB Weld. If your dents are less than 1/2" deep, the JB Weld should be all you'll need. If you send off the pipe for repair, the JB Weld would also work well getting rid of any remaining dents or ripple from the straightening process. I've never been a "Bondo repair" kinda guy, but I would use this stuff again in a heartbeat. My mashed-up OEM CR pipe is long gone, but the Retro Rocket and LOP pipes I have here both stay low, under the swingarm. I'm a fan of high pipes these days, and just finished installing a Jemco CR125M up pipe on my 175cc CR (lots of work, but worth it - just thought I'd mention it in case your '75 turns into a rider instead of a restoration). Jemco may make a CR125M low pipe too. Ray |

The DG pipe is lower than stock and comes out straight. Here's a link to the VDRNW page that has a picture. Coll http://www.siegecraftnw.com/VDRworks.htm |
