Good maintenance on your bike begins with changing the oil regularly. The more you change the oil, the less wear and tear there will be on your motor. However, every time you change the oil, not all of it is removed from the bike. In an average motorcycle, even after all the oil is drained from the oil tank, the motor and lines can still have up to 24 to 30 ounces of old oil in the sump. You could pull the drain plug from the motor to get rid of the remaining oil, but if you've got an aluminum case with a steel plug, the threads can get stripped very easily.
Rogue Chopper has come up with a way to change and flush all the old oil from the motor every time you change your oil. This means you will have more oil life, since you'll start with all-new oil each time.
