Note: Many people in countries that sell oil in quart containers simply use 3 quarts of oil. The lack of a little extra oil makes no appreciable difference in performance or longevity.

Maintenance intervals

Everyone has their own opinion based on their personal experience and riding characteristics. I follow the Moto Guzzi guidelines and change the engine, transmission, and drive box oil every 6,000 miles. I also change the spark plugs and check and set the valves every 6,000 miles. I change the fork oil and brake fluid yearly.
