I could give yo ua laundry list, but I just checked the fluids, changed the plugs and fired her up.
That's what I'd do to see where she stands. or maybe even just change the oil first.
Plugs
Ignition
timing
carb clean/sync
brake system inspection
fork oil
Valve clearance
cam chain adjust
drive chain clean lube and adjust
inspect those tires they're the most important thing in my eyes.
