    Large metal debris in first oil change

    I have two identical, new, 2018 GTI SE 130 PWCs. I just got each to 10 hours this weekend, so I changed the oil and filters.

    On the first one, there were very tiny fragments of metal in the filter pleats. They were so small that you couldn't even see them unless you were in direct sunlight.

    On the second one, however, the fragments in the pleats are larger, visible even under a fluorescent overhead shop light. I would estimate they're less than 1 mm in size. But here's the kicker. When I lifted the filter out of the housing, I saw a long shaving of metal sitting at the bottom of the housing. I've attached a picture.

    Due to the shape and length of this shaving, I'm assuming this was leftover from a bore-out at the factory and was missed while cleaning the block before assembly.

    This is my first time working on any Rotax engines. Is this typical? Good thing a have the 3y warranty?

    (During break-in I used only the green learner keys, to help make sure I wasn't too hard on the engines. I didn't baby them, but I made sure to always let them warm up at idle, and then low-speed, before taking off or doing any faster maneuvers.)
