Ducati Pickup adjustment

So the Ducati needs a special tool to align the ignition pickups, costing nearly 200 quid. So I thought I would use plasticine pushed onto the pickup faces, then replace the cover, turn the engine over and then see what's what with the plasticine. And it worked (to some extent). Obviously this doesn't check the angular position, but should enable me to get the distances right. You can see on the photo where the rotor has scraped the plasticine, the thickness of the plasticine will give the gap and as can be seen on the RH pickup, it also shows the angle of this pickup is not parallel to the rotor. I adjusted the RH pickup (which was the cylinder not firing) to be square to the rotor.

The second photo also shows that the rotor has also (at some point) come into contact with the clutch gear.
