I don't think it matters 10w30 or 10w40 in this motor. I have a hunch that they did this a couple of years ago to improve mpg.
But as you can see you can get much better mpg by making the bike have better air flow.
I have a lot of Spectro 10w40 syn. oil left over from my store and will switch to it when I feel I have it broke in.
