Thanks all for your input, Ive spoke to the dealer who is sending me a new header out in the post, I spent the time yesterday stripping the bike down and checking everything over, gave everything a check with a torque wrench, greased everything up because from factory, it’s as if they’ve forgot what grease is. I’ll be keeping hold of my 2016 factory for a little while longer, just incase anything else goes wrong. I’m assuming covid has had a lot to play in the quality drop but who knows.
