Hey Tony,
You don't have to remove the tank to pull the plugs. Look under the tank right above the finned cylinders for the sparkplugs. If each are behind a chrome tube, you still have your Air Injection (AI) system in. You will need a thin-wall 18mm socket to remove the plugs. Gently pull and twist on the sparkplug wire caps to remove.
If you want to pull your seat and then your tank to see what's up under there, check out the Tech Vault. A wealth of information!!
Here's a direct link to the Tech Vault for removing the seat(s) and tank:
