NHTSA recall 07V066000

What's wrong: On certain motorcycles, frequent short trips particularly during cold temperatures, can cause water to accumulate in the oil tank, and when the engine is running, escaping water vapor can condense on the oil tank air bleed valve. In freezing temperatures, this water could freeze and block the air bleed valve.

Why it matters: It is possible that a pressure build up in the oil tank could cause it to rupture, allowing oil to leak onto the rear tire. An oil leak could cause a fire. Oil on the rear tire could cause loss of control.

The fix: Dealers will install a new oil tank cap containing a valve to prevent overpressure in the tank free of charge. The recall began on April 10, 2007.
