Is there any chance you might be able to repair the original?
Not properly, no. The protrusion that is supposed to guard the drain plug has sheared off. So even if I replaced the drain plug and made it liquid-tight it would be lacking protection. I wouldn't want to risk a catastrophic failure, while riding, that could kill my engine or even spray oil on my rear wheel and cause a crash. Not worth it!
The three oil pans that I saw on eBay were all listed as "great condition" but the pictures clearly showed a similar failure to what I experienced and the sellers had ground the protrusion down to make it less jagged. It's disgusting how scummy eBay sellers can be.
I have another motorcycle that I can ride, in the interim, if the weather is nice. It's just frustrating because my Kawasaki is the better "winter" bike, by far, and it's the only one I will ride in rain or really cold conditions.
I don't understand how Kawasaki can be currently producing new C14's using this oil pan but not have ANY available to sell me? I know the C14 is NOT a high-volume seller, so I can't imagine that every single oil pan is allocated to a VIN on the production line.
