For most of the 150-200cc Taiwan bikes the engineers that wrote the service information say at 600km (or 300 MILES) the valves need to be adjusted to spec, also our bikes come with break in oil instead of regular oil which is actually damaging to your engine if you leave it in much longer than about 1000km. There is also break in oil in the final drive hence why they say to change that on the 1st service. A note to zombie, why should dealers or Kymco for that matter pick up the tab on servicing? Your not buying a $50,000 Audi, service costs are the owner of the vehicles responsibility and if it is too expensive there is a plethora of information even on these forums to learn how to do it yourself. It is very important to get the valves set after the first few heat cycles the engine goes through because those first heat cycles expand and contract more than when the engine is "broken in". They guys over in Taiwan are not stupid and do not profit on setting the first service at 600km, so there is good reason to do it!!!!
