Bajaracer how much time was on your engine when the clip came loose?

My first Ninja died this past weekend. I had installed the new clips before ever firing it. It lasted 5+ gallons before the rear bearing came apart and ate it up. It gave me warning but I ignored it and paid the price.

I have a 2nd Ninja I bought as a back up. After replacing the clips on the first engine I didnt want to go through the hassle of doing it again. I figure as hard as it was for me to get the originals out to replace them they had to be OK. Now that I am down to one engine I am rethinking that position.
