I bought these washers to use with a Honda Metropolitan Scooter CHF50 oil drain plug My scooter is a 2008 model year It was a good direct replacement for the crusher and we are almost the same size, just a little thicker. Check out my photos of these new shims versus the stock Honda shims. They fit very well on the drain plug and leave no room around the drain plug inside or outside - see photo of them on the drain plug - I fitted them.
