i would put a new plug in it ,change the oil and filter,clean the air filter,change the gear oil,top up the brake fluid,adjust the rear brake if its a drum brake as the older ones were,check the tyre pressures and set the valve clearances,and maybe spray an bit of lube on the stand pivot ect... the brakes may need a clean up too the calipers will be a bit dusty.
