be careful with the petrol, back when i had my bike, i tried 'shell optimax' (98 octane) with an ngk plug and the bike fouled like crazy. Put normal petrol in and it was fine.
Figured its because these bikes have quite weak ignitons, could not ignite that high of an octane while cold-warmish (fine once HOT), and the plugs just fouled. Also optimax and the others have cleaning agents etc which can also foul up the plugs on these bikes.
Try using 95 octane 'premium', not the fancy name stuff
Found this out, If you buy a brand new Ducati, and they find out you use optimax etc it acutally voids your warranty.
but hey if it works for you its fine then
and with that scooter, besides the carb and filter, have any other mods been done? what type of carb is it? a friends 43cc scooter is in NEED of mods :shock:
