"Break-in" today is a kind of a religious argument and I am unqualified, as just about most people are, with particulars. But just read this.
@Boosted Cycle Perf is a sponsor of this site. He is well-respected for adding turbos and superchargers to all kinds of bikes. Here he explains the reaction of new modern engines, as he a professional physically monitors them during the process. He puts on a turbo, and for a brand new engine
revs it to the moon.
IDK, looking at the pic of parts it looks like you'd just tear down the bike to the point like your doing an air filter and full exhaust install..... Basically everything there from the intake side of engine ad the exhaust side.... No new injectors or this n that. If you get the right kit I’m...

Yes that off-road oil with excessive zinc is bad for engine internals. No, the zinc nor the synthetic aspect did not kill your engine. There were other factors involved, so do not worry about it.
If you look at that 540 Rat engineer's ratings list of oils,
motorcycle-specific oils are at the very bottom. He is doing an
ASTM metal scoring test and motorcycle oils are outright terrible on that test! For parts that contact each other, like valves, rings, gears, the motorcycle oils (except the boutique ones) are utter failures. That pretty much indicates that these motors are so balanced, so well-made, they will be fine with just about any oil. Just use a motorcycle oil for the clutch. Don't spend $20 per quart, do not get a generic oil but then do not worry about oil at all like you today, and pick any oil in between. Feel free to use a synthetic too. If you like the shifting of a conventional you find, for goodness sake use that. Forget about the crowd that lives and dies by their boutique oils and laboratory oil analysis. They are some kind of nuts and they have misled many people.
For any of you who are racing and generating massive power, 540 Rat has published that the new Quaker State synthetic in the green bottle is a miracle on the metal scoring test compared to anything he has ever tested. I have no idea if that will work with a wet clutch, right? But if I had massive money in a high-power engine, and it worked with a particular clutch setup, that is what I would use right now to extend the life of every expensive component inside my motor.
