be careful with the bevel drive dukes! I used to run a 75 750Sport and found that in winter a straight 40 grade oil to be the best and in summer I used Castrol GP50.
The old dukes were better being run on a monograde oil, do not use a multigrade. GP50 is still redilly available and i would strongly recommend to tell you friend to use it.
