As a rule, do not rely on level plugs. Measure the quantity needed, put it in, and be done with it.

On the Eldorado rear drives, Moto Guzzi placed the level plug in the incorrect location on some of the rear drives. Check out the photos below to see the difference.

Martin Baechle sent me the following photo and description of his alternative to the original Guzzi fix for incorrectly drilling the level plug. In Martin's own words:

In when I rebuilt the Eldorado I created a fix for the wrong height of the level plug, that is very similar to the original Moto Guzzi fix - from which you posted the pictures. I simply used hydraulic tube fittings of automotive brake parts, I attach the picture. It works good with no leaks and I most likely will repeat that for the V7 Sport.
