If your taking it to the dealer to get them to set your mixture screws, you may as well get them to set up your jets.

As you said, this is not a pure science because every bike is different (pipes, parts etc.) and they are also from different locations (sea level or up in the mountains) which will determine different jet size.

Good luck, hope you get it sorted...
