For reference sake, how many miles did you ride in that 2 years? Oil changes are really more mileage dependent than time, though the advertising would have you believe oil goes bad just sitting there. Acids can develop, but that's another thread. I don't think your method is a problem for your needs.I used to change it every time. Now I am lazy and do every other oil change or once every 2 years. By just changing the oil, I do not have to take my skid plate off and it makes everything easier.

I cut open the OEM Yami filter that was installed for 2 years and it looked great at the end of the two years.
