HITACHI Emulsion Tubes / Needle Jets

The Virago's carbs have an ability to wear out the "needle jet" and cause excessively rich low rpm running - both at cruise and at full throttle / low rpm. The Virago isn't the only bike that does it  - most big bore bikes will wear them out.
If your Virago is getting mileage in the 20 mpg range, I'd look at the needle jet wear.

Factory Pro makes stock replacement needle jets (also known as "emulsion tubes"). Improvements in the original design include hard surface nickel plating.
The XV1000 and XV1100 use the same replacement Hitachi item.

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
