I would wait for some more miles before going to synthetic, but other put it in right away without issues. Both of those brands are popular, just make sure don't use an oil with friction modifiers. I usually use Motorcycle specific oils that are labeled they meet the JASO standards, but last change I tried Rotella Syn. It has been good so far and I know many other riders use it in their bikes.
