Answer
Hi Mike.
 When in doubt, use the factory recommended oil.  Outside of that, if you live in a hot climate, then use a good quality 20W50, otherwise 10W40 works just fine.  Remember to use only natural oil with natural and synthetic with synthetic.  If you use a hybrid oil, you can mix either with that.

Have fun and ride safe.
