I had a 85 cr 125 in 85-86 and I put a Pro Circuit pipe on it. I had to take the ATAC system off the bike, but other than that, it ran great!

With the ATAC chamber on your cylinder it might be hard to get a newer CR pipe to match up. Not sure if Pro Circuit removed the chamber on the 250, but DG did. They included a new manifold with the pipe....like this

Yes I've sold my chamber on already thinking that worst case scenario I can get a dg system as they're still available off the shelf. My main question I suppose is whether the dimensions and bracket positions of the 87 system vary that much so it may be too much of a cut and shut job to get it to fit

Mateaton,
I have an '85 CR250, been following your restore and other posts about this bike. I have the DG system on my bike (came that way when I bought it). No ATAC chamber. I also have a pro-circuit pipe, but I have never tried it. I sent it out to a pipe repair shop to have some small dings fixed, the re-painted it. It uses the ATAC chamber and I have never felt the need to buy one. If you are interested, let me know. I race mine, so not concerned with restoring it to factory specs. I plan on rebuilding mine after this racing season.
