Review on Precision Machined Aluminum Universal Motorcycles by Edris Holwell

They are poorly made as they are slightly oversized threads so they can easily cross. They are also too long for the valve stem seal. They don't fit in any of my four cars or in my F150. Pretty sure they are non-returnable because they already know they will not work for anyone who has any idea how a valve stem works. Revain must remove this item and return any remaining stock to the manufacturer.
