Why will VT 750 shadow only run on choke?

If a VT 750 Shadow only runs with the choke engaged, it may indicate an issue with the fuel system, such as a clogged jet in the carburetor or a dirty air filter, restricting airflow. The choke enriches the fuel mixture, compensating for these issues. Additionally, it could be a sign of a vacuum leak or a problem with the fuel lines. In any case, further diagnosis and cleaning or repairs are necessary to resolve the underlying problem.
