Hi, I would like to know how to open and repair a ducati CDI box.

In particular how to remove the resin around the circuit board.

And which resin to use to seal it?

Thank you very much.

    It's a secret eveidently. I've never seen this done or heard of anyone in the US doing it. I have tried to cut them open playing around, but that's a lost cause. My guess is it's dipped or had some type of liquid solvent applied to the filled side.

    There are some vedios on utube you can watch for I believe entertainment purposes that shows you how to open to see something obvious broken and put back. But these are on motorcycle. I SAY AGAIN FOR ENTERTAINMENT PURPOSES WHEN YOU WANT TO LEARN OR ARE CURIOUS. 

    IF it's an aircraft you just can't pull over and call a tow truck. You are coming down. 

    Every thing is very expensive. I think it's about 1500 dollars for the 912 rotax. Everything that supports the 912 to keep pistons firing is very expensive. 

    I just replaced the carburator floats on my 912ULS, 150 dollars a pair. One old set was 12 grams and other ok. The old 12 grams was causing fuel to come out of vent tube at low rpm. The floats pair should be 6.5 to 7 max GRAMS weight. ROTAX DOES NOT MAKE MANY PARTS THAT SUPPORT THE ENGINE. USUALY WE ARE DEPENDANT ON SUPPLIERS AND THEIR QUALITY CONTROL EVEN ROTAX. 

    WELL ONE JUST CAN'T TAKE A CHANCE. IN MY CASE. I HAVE TO PAY OR STAY ON THE GROUND GIVING UP FLYING, DRIVING AND CALLING A TOW TRUCK WHEN THE CAR OR MOTORCYCLE STOPS WORKING. THE PLANE IS COMING DOWN HOPEFULLY NOT ON TAKE OFF.

    Thank you for your answers.

    In France we talk a lot about ignitech cdi.

    They are clearly "cheaper" and everyone says they "work better".

    The problem is the "they say" but nobody knows what's inside.

    Some even change the original curve...

    "In France we say" yes, I know that in France we are necessarily wrong ...

    But having tried it on 4 Rotax 912S engines, I can tell you that it works delivered with the same advance curve as Ducati / Rotax.

    Having tried on a test bench to change the advance curve, I can say that there is no point in changing it compared to Ducati.

    We obtained a much lower idle, but damaging to the reduction gear.

    I say no more ... I'm wrong ...

    It's much cheaper, that's why the info is spreading "in France", knowing that we are all wrong ...

    In Paris, you are probably right about everything, knowing that Paris is not France!

    This may be the explanation, the bashing "France"
