With bike on center stand, when the bike is started after sitting cold then the rear wheel spins slowly until bike warms part way up (1-2 minutes). My previous Maxim's tended to do this. Don't know the cause, but I use Castrol 20w50 4T (motorcycle engine oil for these "wet" clutches) and just changed both oil and filter. Previous oil change was done a year ago, and I rode just over 1,000 miles between oil changes. A potential buyer wants to know.
