Percentages of failed plastic oil pump gear in 1999 kawasaki nomad motorcycle?

would just like to see some numbers on this. they are posted somewhere. i jusy can not remember or fine where. thank you|||The ones that failed were most likely repaired by dealers under warranty up until last year. Kawasaki no longer warrantees them after 10 years. Many others whose oil gear did not yet fail replaced them pre-emptively with an aftermarket gear. I have never seen any hard numbers on it, though.
