Thanks for the reply- perhaps it is a D [or later] Model CDI  ignition that I want.
Any advice is appreciated.
Complete motors [including ignition electrical] are also welcome.
Thanks

I did not know the CDI was trouble.
I am good with points, and know how to measure and set the timing.
I was just feeling a bit lazy, and the flywheel has some pitting-so I thought CDI conversion .........

cdi is great when new but a 30yo cdi box is gunna have dried out caps in it just waiting to short out between the plates,a quick search on ebay gets a new cdi box for 249 plus post from germany and youll need the matching stator/rotor and H/T coil where 31 aussie gets you new points/condensor and a trouble free system. if you wanted to give it a supper birthday replace the H/T coil as well and get your rotor soda blasted if its not badly pitted or replace it with a good used rust free rotor

Is this a road/trail or a race bike? There a infinite number of ignitions you could bolt on instead of a old DT ignition.

I bought this little fellow recently which is a C model and was surprised to find that it runs points when my 400 C model has CDI. Not exactly sure what I am going to do with it yet but I would like to try and get it running to see what the motor is like.  Compression seems good but currently it has no spark so I too was wondering what options are available as far as new ignitions are concerned.

You would probably find if you gave to pionts a clean with a bit of emery tape through the hole in the flywheel it would bring the spark back to life. Don't be fooled by the hype into believing that a CDI will make it perform better, a lot of the early CDI's had very strange advance curve.
