Kaw crank bushings
I have had the same trouble and have in my desk at work a list of 2 companies that will make that bearing for you . I warn you the price is not for the weak of heart . They start for 1 bushing at around $65 and drop fast as you increase the number you have made. The trouble is you only need one.
I have several for the 19 kaw but none for the larger one. Different size crank. I will post those companies tuesday when I get back to work.Oh ,, you can most likely find a short block motor around on the internet for $600
