Cruisin' Guzzisti
Not positive how Guzzi's arrive at the dealer but Hondas arrived and as a dealer you would never look at the gearbox or master cylinders because those were filled "correctly" at the factory.
I'm not assuming either happened at set up, but considering his mileage and his statement that he let the dealer touch it I presume the overfilled gearbox occurred at the break-in service.
The master cylinder I'm assuming the gasket wasn't seated properly. But if so, how much time did it take to show up? Were there other factors (screws loosening in service, not checked during break-in service or happened before that, was running 90 mph a lot part of the equation, etc.).
