Congrats and welcome!!
550s r cool, want one
The main thing seems to be to change the oil reasonably often and adjust the valves often. (Both are easy tasks so don't worry.) I unfortunately can't speak about specific intervals as I don't have one yet - search the forum.
Anything in particular you're thinking about?
How many hours on it?
p.s. - something to consider is reading up on crank axial play, you want enough of it
