Well - Since you did say 'anyone' (not just sportsterdoc) I'll chime in here...

If you put a 1/2" spacer under the float side of the carb mouth you will get the approximate 15°-20° angle that is needed...

This once again demonstrates that the original Keihin parts are usually most appropriate for the correct operation of the CV40 carb...
