ok, so i just took off my carb and stuff and see the reed cage. I can barely get in there to see them. How do i pull out the reeds and stuff? There a 4 little screw ends sticking up to keep me from just pulling it right out, but they have no end to unscrew them. How do i know if i need new reeds also? Here are a few pictures.

and my bike (i took the handguards off though and it looks so small in this pic)...
