Could be a couple of things. Can you narrow down where the knock is? Right or left side? Is it constant? Changes with RPMs? More so under load? Sometimes, when carbs are out of sync, motor will run rough or sound like it's knocking. When was last time they were synced?

knock is constant and sounds like both sides.power seems good standing still.i dont know about riding because i dont want to trash it.
