Can't go wrong with "motorcycle oil" if you're willing to pay the price.
10 years ago the need for "motorcycle oil" was 100% B.S., now it's merely 90% B.S. Many "car" oils now have reduced zinc and phosphorus and don't meet JASO spec.
If you want synthetic, Mobil 1 15w50 "car" oil is fine. Most any of the cheap 15w40 "diesel" oils are good. Rotella 5w40 syn and 15w40 dino meet JASO standard.
If your clutch fluid is more than a year old, bleeding it out and replacing it with fresh should improve the 1-2 shift.
