do you have to remove the top chain to change the tappets ????

To do the tappets you need the camshafts out, to get the camshafts out you need to take the sprockets (and hence the top chain) off. You wouldn't actually need to remove the chain, but you would need to disconnect it from the camshaft sprockets temporarily
