2018 xmr motor knocking.

I have a 2018 outlander 570 xmr. This weekend I was riding at max speed and all of a sudden it lost power dropped to around 45mph and then it picked right back up. Got it home and now it has a heck of a knock. Almost sounds like it in the bottom end. Any advice on what it could be?

Pulled primary clutch off. Cranked motor. Still knocking. Bottom end it sounds like. Now my question is instead of doing the big bore kit on the 570 which takes it to a 740. Will a 850 motor bolt up to everything?

1300 miles. I was told it was piston slap. I’m gonna run her till she quits. I’ve read other forums that say they have ran there’s with piston slap for very long periods of time.
