My Feedback: (11)

We have no idea what you are asking about. There have been rare failures of the piston pin retainers, but that doesn't cause the wrist pin to grind against the cylinder liner. When a retainer fails, it is the part that causes damage. But again, it's a very rare happening.
We've never heard of connecting rod problems.

I have recently heard from two internet comments about the wristpin circlip breaking on the large Super Tigres and scoring the cylinder liner. Any comments about this in addition to what has already been said?
