I didnt realize that Iowa was for sale!
I lived in Cedar Rapids for 4 years in the late 1980's.
Which bike did you get? I dont think any of the Vstars have a tube over the drive shaft, that chrome rod you are looking at is the drive shaft.
Edit: after googling this apparently some vstars do have a tube over the drive shaft? I guess yamaha had some extra tubes in the factory and could not think of a good use for them! :^O
