Coolster 3150DX2 "jerking" and loose throttle?

Hey guys, still trying to figure out what's causing this new machine to "jerk" when going forward. If I go in reverse, it's smooth. Soon as I put it in forward and push the throttle, it jerks and bounces and I hear loud clacking noises. I thought it was the chain which was super tight so I adjusted it where it has some play and the issue is still there. Also, I'm not sure if this is related but when I press the throttle in (reversing it going forward), the engine revs but I have to press the throttle in far for the atv to actually move. And sometimes I hear a grinding sound and loud clanking sounds when it does start moving which is accompanied by the "jerking" of the machine. Any ideas on this?
