Analysis of the wear points on a heavily used Keihin PWK Airstryker carburetor. I suspected this carburetor was worn out because the motorcycle it was installed on (Hard Times) ran extremely rich despite proper jetting and adjustment. This style of carburetor was used on the Honda CR250, Yamaha YZ250, Kawasaki KX250, Suzuki RM250, and many other 2 stroke dirtbikes from various years.
