Question Loud Rattling sound coming from engine when I rev the throttle

Hey guys ... ok so my engine was seized up so I decided to take it apart and see what was up ... it turns out the piston arm was bone dry ... so I oiled it up really well , and used a flat head screw driver to manually turn the gears and move the piston up and down ... put everything back together , and got the bike running again ...

... only problem is now when I try to get up to speed and really rev the engine , there is a really loud rattling noise that is really annoying and also when I just let the engine idle it shuts off ...

any ideas what might be going on ? thoughts ?
