My mom's 2003 Vulcan had a rotted pcv elbow on the top left side of the motor when facing the car. Remove yours and take a look inside if you have the same setup.

How did you check for vacuum leaks? Have you scanned for diagnostic codes yet? You could use a scan tool to monitor live readings that may assist in diagnosing.
