Default 2015 Iqr 600 knocking

Need help getting my iqr to stop knocking on decel. Just went through the whole thing. Compression is dead even in both cylinders, new plugs, fresh 93 gas, cleaned carbs, cleaned exhaust valves. It still does this knock thing after I rev it up. Whole motor shakes aswell. Have a video of the noise before I did all this, still sounds pretty similar. Thanks

What does that sound like? It only does it after you rev it. Does multiple “knocks” if you will. Doesn’t sound too good. Seems to run fine though.

Sounds normal but I think you have at least one broken motor mount.

Well that’s good to hear. Really thought I had some mechanical issues going on internally. Guess that’s normal for this sled?? Where do I check for broken motor mounts?
