I think that we should consider making a couple of changes to our trackday bike prep requirements. 1) Oil drain plug should be siliconed. People often re-use the crush washer, and when you do the drain plug is much more likely to spin itself loose. Silicone is easy to apply, and when removed leaves no trace that the bike was tracked, unlike drilling for safety wire. 2) No gopros on helmets at trackdays. Lipstick cams only. This one is easy to enforce. 3) No aftermarket oil filters. Maybe this one is a little harder, but I think with all the problems it is best to just say no. Worth discussing.
