I'm looking for another oil for my pair of Nytros too. Not only does it call for a 0w-30 API SG or higher, but it also says JASO MA or higher. The JASO is for motorcycles with wet clutches, yet the Nytro doesn't have one so that spec confuses me. I was all set to run M1 0w-30 AFE until I stumbled upon that little tidbit.
