Hey guys, have had a BT-200X for a few months now, everything seemed ok, until randomly the "twist grip throttle" on the handle bars (sorry, don't know the exact mechanical terms) started getting stuck when you would accelerate. It would literally not twist back by itself., unless I twisted it back myself.

Thought it might have been a spring issue, but it wasn't. It was literally like the twist grip itself would get tight/stuck and have to be twisted back the opposite direction.

So, like an idiot, I unscrewed the plastic twistgrip thing to see If I could locate the problem.. I could not.. and I can't figure out how to put it back together either! doh!

anyone know of a good site, or video or resource I could consult for help putting it back together? i' at a total loss.. nothing broke or snapped when I took it off, but the pieces just don't seem to fit back together correctly. thank you

Here's a pic of the twist grip.

And the parts that came off
