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 ?

Might be Marley's ghost. :) What kinda engine ya got?
 
how well is the engine mounted?

i had a similar problem on my bike originally, as the motor whirred up into the higher rpms it would get real loud since it was vibrating so much, changed a few things out and locked that baby down and it was good to go, mite wanna give it a try yourself.
 
Its definitely coming from inside the engine. Probably the needle bearing ... im gonna take it apart again later and see ... I have the engine mounted pretty well. Its 66cc stinger
