Scooter Gear Oil

How times change gear oil? and the oil regularly as well?

I would check the gear oil to ensure that its winning regularly and change it whenever you can tell a difference in color or if you see any kind of dirt or metal ... for a regular oil change every 3000 and you will be allowed

YKA know, I love cars honstly peices, but you want advice in the form of another guy .... lol
