Any one of those would be fine. I like diesel oils because they're more robust than modern passenger car oils and probably hold up better in an air cooled engine. Rotella T4 or T6 is what I've typically run in Kawasakis. If you run it really hard, a 15W50 synthetic is a good choice, but in typical service, it's hard to go wrong with modern oils.
