Hi!

It sounds a bit high - i remember about 350 Euro...

Yes there is - the RD03 has two CDIs, the 04 and 07 have one...

On my homepage there's the instructions - in german... Micha, are you
interested in putting an english version on www.atic.org? I can make
it and send it to you...

Anyway, look at
http://www.uni-karlsruhe.de/~up1j/motorrad/schraub/cdi.html
and see the pictures to understand the following text:

CDI's usually die of an internal bad contact at the backside of the
plug. Replacing them is very expensive (200-350 Euro), but fixing is
easy :-)

Open the black box by milling about 2mm off the backside of the box,
just opposite the plug, so that the hard plastic is gone and you can
see the silicone-type filling. Be careful, don't go to deep! Otherwise
you'll damage the printed card inside. Maybe do it step-by-step.

Remove the filling carefully bit by bit with pliers or a dull knife
(its soft, so it's easy). Now you'll see the soldering points of the
printed card. Re-solder the ones that are opposite the plug.

Now seal the unit again with silicone, but cover the soldering points
on the printed card first with some plastic, since some silicone types
contain acid and in this case you can do the same job again 6 months
later. You can also use 2-compound-glue but that is not easy to remove
if it happens again...

Take a look at the pictures on my homepage to understand my words :-)
and do it similarly with your CDI. I the one of the RD04 looks
different but the basics are the same.

And: no guarantee. Most times it works, sometimes not...
