I think I will use Mobil 1 20w50 v-twin oil, changed according to the manual. It is mainly intended for Harleys, and late model Harleys run red hot. Heat is the main enemy of both oil, and air cooled engines. I run my XT225 and Genuine Stella 2 stroke on the rich side to help keep them cool, but with FI, there is no way to richen the mixture, at least not without an expensive reprogrammer.
