I remeber reading in a mag someone had a new 996 as longtermer and the head bearings were loose causing were handling they were tightned at first service and problem cured, i don't think they are worn yet after 400 miles unless they are faulty.
They have the gold machined alloy carriers that are lighter than the standard 748.
Would they really move that much on the bobbins?
Probably go up dealers on the weekend and get them tightned.
Thanks
