Hi All,

Basically, the idea behind this thread, is that we invite all forum members to post the settings they are currently using on thier scooters, in order to develop a database of information, that can be used by all visitors as a resource for learning and setting up thier own machines.

Please get involved and supply as much info as you can, you never know, you may need to use the resource yourself one day!!

NOTE: Please don't ask technical questions or start discusions about carb settings within this particular thread, please start a NEW thread if you need to have a discusion. This particular thread is for settings information only.

So just add a reply below with your carb set-up and watch the list grow!
