There are actually two problems.
One is the solenoid requiring lubrication, though why it should here and not on any other starter motor I have known I don't know.
The other is the low power to the solenoid, cured by the rewire of the start relay.
There are two windings in the solenoid, a high current one to pull it in, and a low current one to hold it there. the high current coil is shorted out when the contact in the solenoid is made.
If, for any reason it does not make contact, then that coil will pull well over 20 Amps, thus blowing the fuse. Low power to the solenoid will cause this, and as that power has to go through the ignition switch, it is quite possible that the switch contacts are not intended to take it, most switch manufactureres would assume that the start relay is fed from the battery, not through the switch. Guzzi have not yet accepted this.
