You would hope to get a part that will last the recommended service interval but that is not necessarily assured.

And in this case there is NO way to know how many hours were logged on the bike, oil ratio, or jetting that the previous owner had. Quite a few unknown variables to just come out and say it's Namura's fault. 

Do cheap parts cause motor failure or is it that those who see false economy in cheap parts rebuild their motors incorrectly?
