Your scooter's factory main jet size (50cc)

Hi guys, just reanimating my poll from the old forum.

I was wondering which are the most common OEM main jet sizes in our 50cc scooters, so I decided to make this poll.

You may also share some further details such as engine type, what type and size of carburetor you got your scoot with, a 4-stroker or a 2-stroker...

Thanks again for your input!
