Hi,I have been trying to sort the main jet size for my scoot but find it hard to feel or hear any change when I swap jets.Have gone from 50 to 80 and am at 62 right now.Not sure what the standard size jet is-anyone know?The carb is a Mikuni 16-5684 and had a 47.5 Mikuni jet when i got the scoot but the auto choke was full on.Sorted the auto choke but the bike would then die after half a mile.Appreciate any help.
Cheers Andy W.
What are you trying to do with it? Check the plug colour to determine what jet to use, it need's to be a nice dark chocolate brown to nearly black, when the plug's that colour it's right!

Thanks for the advice about the plug colour.
I just want to get to the right main jet and was hoping someone would quote me a size that would do it.
