About 3 years ago I had a DS650 and some one on this thread had bought a BMW motorcycle cdi box and installed it on their DS650 rather than buying a aftermarket cdi for inproved RPM and timing curve. I found one and bought it from some guy in London but never put it on. I got a Suzuki LT 500 R with a Honda cbr600 motor and so couldn't keep them both and so sold the DS. Later I sold the cdi and now I wish I had kept the information on how to install. I think (if I remember right) that one wire had to be moved from one slot to a different empty slot on the cdi. If anyone has any information on this, I would really appreciate it. Thx...Dean
