I have the original Electronic ignition system at my 250 Desmo and would try to set the timing with a stroboscope.
But i am not sure where to find the marks,
There are som at the clutch cover - a line and a dot but nothing at the crankshaft - at least as far as i can see.
Do i need some special tool or are there some other ways.
Per
setting the timing

HI Per, I don't know what the advance range on you motor is but on my old 250 i just set the static timing to give me the most kickback i can stand and its still not advanced as much as the motor needs for max performance!! Crude yes but i actually want to ride and be able to restart on the road, I must be a bit odd as no one else rides the things regularly.

Hi Per, At any more than 5 degrees static starting becomes unreliable on my 250, I dont think my AAU gives the specified advance either, perhaps a couple of degrees less,so full advance is not really enough,I dont recommend kicking against the compression,bad for gears and stand. Best to ease past compression before kicking.Widecase has better gears and stand.My bike is faster with 10 degrees static but a pig to start and will stall too easily. Thats no good i need to ride!!.

Not exactly on topic however.
Static timing.
There is a dot on your ignition rotor and a corresponding mark on the stator.
Assuming you know how to use a degree wheel and a piston stop to find TDC. Align the dots as follows for each model.
250 - 52 degrees BTDC
350 - 47 degrees BTDC
450 - 36 degrees BTDC

I did not use the word advance.
I was working as a mechanic on Ducati motorcycles, when these models were produced. At that time there was no information available on the electronic ignitions. This information was supplied to me by the factory in response to a telegram that I sent to them. This was my chosen method of verifying such details as quite often the information was unavailable or incorrect. To be pedantic, I am sure you are aware that the same ignition parts are used on the electronic ignition singles, but the timing gear is one tooth out on the smaller models, hence the discrepancy.
