The sized screw holding the oil filter door was the least of my problems as it turned out.
What followed was a rookie mistake…I went out into the fields to fly my FPV drone and dropped the only set of kets to my KTM somewhere in a huge field. Sadly they were the only keys I had. (don’t ask me why 🤦🏼♂️…)
Looks like I have to choice left but to order a whole to set of locks and keys to replace on the bike.
