Transport CanadaMedium Risk
Defect
On certain motorcycles and trikes (three-wheeled motorcycles), the airbox backplate breather port may be blocked. As a result, pressure could build inside the engine crankcase. If this happens, hot oil could be ejected from the fill spout when the dipstick is removed.
Safety Risk
An oil leak could create the risk of a burn injury.
Remedy
Harley-Davidson will notify owners by mail and advise you to bring your motorcycle to a dealership to inspect and, if necessary, correct the breather port opening.
