Nice bike.
had a 83 V65 sabre, still miss it, Done 70 000Km with it before selling it.
My .02$, you surely already know that...

Smart charger to keep battery full, low voltage battery is tough on old bike electronic.
don't cheap out on tire.
premium fuel only.no cow fuel.
Change oil frequently.
V65 need to see WOT and 8000rpm once in a while.
