My much delayed (589 miles!) oil change was finally done this morning after a few false starts! A word of warning, the Philippines YouTube videos on the subject seem to show a different model to the UK one I have and the procedure is therefore different!
The good news for owners is that all this is possible without having to remove
any plastics! If it helps others, mine has both an oil filter (see second photo) accessed using a 24mm socket and an oil screen located just to the left of the 17mm oil drain plug.
I first of all ran the scooter for a couple of miles to warm her up and then removed the filter having first removed the filler plug:
Removing the filter revealed all to be in good order so this was replaced to await a change next time.
Then around to the lefthand side of the bike (as you'd sit on it) to locate the oil sump drain plug. This is the RH one of the two bigger nuts visible, the one on the left is the oil screen filter.
Finally just to prove I did drain the oil!
After a while I replaced and tightened the sump plug (having first checked the crush washer was OK) and then replaced the oil. The manual recommends 0.9L, but having drained my oil filter earlier I'd guess it was about 1.0L or a little over before my dipstick (inserted fully home) showed the correct oil level.
All in all the whole routine - even allowing for the YouTube puzzlement - took less than 45 minutes and I expect it to even quicker next time!
