@bxc, second what Stig writes.
Since I had recently (though on way higher milage) two times (on different KYMCO scooters) destroyed gear bearings and oil seals,
(need not neccessarely to be on your LIKE too)
I would recommend, due to age and maybe unknown service history, to change gear oil (180ml of NON hypoid 70W-90) any brand.
Change of brake fluid (DOT 4) might be good to, IF not done recently.
If you technically inclined, take those two 12 mm muffler nuts off (cylinderhead-pipe), put copper paste on it to avoid later troubles WHEN you HAVE to take them off.
Don't know how good your tires are, but if you change the rear tire, change the bearing within the sidearm too, goes at once and costs little.
Take your battery out (footrest area) and clean terminals, fuses and put some silicone grease on connectors.
Otherwise as Stig wrote, a real flawless and beautiful scooter.
Best regards from Italy.
