Wouldn't hurt to check cam-timing. Doesn't explain bad cylinder switching from left to right though...
I'm worried with new data from other thread that bad plugs are a thing with new-gens. When he switched from new plugs to old ones fixed the issue. Haven't responded with which brands & model those plugs were though.
1. Which brand & model are your new plugs? Have you tried setting gap to 0.025-0.028" ?
2. Also do you have any really old plugs that you've used on another bike that you can confirm works 100%? Then try them on this bike.
