+1 on everything. As far as motor oil, it is more important to change it regularly that what you put in it. If it has not been changed for a while, maybe run some Rinsoline or something like that in it for a while. The problem is the sprag clutch in the starter, if it gums up it is a royal pita to fix. Regular changes will keep it happy. FWIW, I've been running 10-40 Pennzoil or Valvoline with a PF53 AC Delco filter for the last 150k miles and the bike seems happy. The first 40k I put pricey stuff in it. And don't forget to lube the little barrel that holds the clutch cable in the clutch lever. If it freezes up the cable will eventually break there.
