Conventional oil for break in so the rings can seat well and also a proper run in without a lot of idling or prolonged running at one low rpm range. By fluctuating the rpm's you help the rings to seat better.
+1000. Do NOT use synthetics. Use a motorcycle grade oil that can live in that tranny. I think I'd wait a few thousand miles before switching over to syn's myself. Has worked well for me in the past. Some of my bikes I never switched over.
