Loud cam chain noise/ sudden drop in acceleration

Hey everyone, Riding in to work this morning around 5k rpm had a sudden loss in acceleration then back to normal. The engine now makes even more rattling noise/tweeting. Also sudden jerky power loss 3-4k rpm and engine shudder/vibration that goes with the power drop. Dropped it by a shop scared to drive it thought I might damage it more. Any ideas what's wrong?

Could be that the Top / Rear engine balancer shaft bearings have come apart. Pull the flywheel and the inner cover to inspect all of the externally visible engine balancer chain, sprockets, guides and LH bearings.
