I've been riding commandos since the 1980's. I've had 2 750s's over the years, but for the past 8 years I've had an '74 850 roadster. I was lucky enough to have some one to work on them, but now my son is biking with me and we want to start light work on them ourselves. For instance I want to change my oil but my Chilton's book doesn't explain the procedure. What is the best way to change the oil. I also have a champion h101 filter and I am going to change that out too. Also what type oil should I use for the change?
