Hi Tom, welcome to the board!

The first thing you need to do is make sure the carbs are spotlessly clean, including the small, nearly hidden passages, etc., and also return them to stock, with genuine Keihin stock size jets. Trying to get it running right with aftermarket parts will be a long and questionably successful job.

If you like, Ducatiman here on the board is expert at doing this, and can get them into like-new condition quickly.
