Just dont abuse it, these things are pretty darn tough, that and ebay for OEM and NOS parts galore for dirt cheap. Like my starter I replaced recently, I bought it 5 years ago when I found an OEM with 1200 miles on it, still shiny/greased for 12$. The orig stator died with like 2k miles, but other than that stuff lasts,.. : forks 95k, fuel pump 92k, radiator 95k, Ive done all cables each only once, timing chain tensioner at 75k,
Oh and almost forgot, they did the valves about a year after I got it ,around 8k miles, second valve job was at 92k. I would suggest a shorter interval.
Ive used reg (not synthetic) 10/30 oil changed every 2.5 to 4k miles, NHK plugs, cleaned orig air filter 5+- times er so. I use the lucas marine grease for chain. What really amazes me, Im still on the orig clutch which feels soft to pull (which I like, getting old) but seems to have rock solid discs still, though I just ordered the inevitable EBC plates 10 min ago : ).
