change that oil and filter and the final drive/differential fluid at about 300 miles, then again at about 800miles to get out all that metal. most use a conventional oil for these first two changes since it's not in there that long then switch to a synthetic(if you like) after that. (you can use a synthetic in the diff from the first change since it only holds 4oz so you're not wasting that much) if you decide to stay w/conventional oil, i would say change the oiland filter at no more than 2,000-2,500 mile intervals. Synthetics, I use a 5,000 mile interval and change the diff fluid every other time.
the general consensus i've read on here is:
the first two changes conventional oil-any 10-40 "name brand" or the honda GN4(I'm partial to Valvoline and mobil myself for conventionals)
then, if you decide to go synthetic, either mobil-1 15-50 or Amsoil 10-40
(from all that i can read you need not spend the extra $$ on "motorcycle specific" oil-unless you're going Amsoil, then i think it is the same price as the "car oil")
for your final drive/diff. Mobil-1 or Amsoil 75-90
finally check bare's site for desmog, ground fix and headlight rattle fix instructions. and he has oil change walkthrough also.
