a possible solution for this problem would be inflating your custom menu inside the activity hosts your ViewPager and getting a menu reference as below:

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
     getMenuInflater().inflate(R.menu.custom_menu, menu);
     customMenu = menu;
     return super.onCreateOptionsMenu(menu);
 }

after that you can easily hide/show the menu's items without any delay inside onPageSelected method as below:

 @Override
 public void onPageSelected(int position) {
  switch (position) {
        case 0: { 
           customMenu.getItem(0).setVisible(false);
           break;
        }
       case 1: { 
           customMenu.getItem(0).setVisible(true);
             break;
        }
     }
