first you need to bite the bullet and get a full exhaust and filter or your cam and carb will not be able to push the airflow that is needed to get the most out of it. Think airflow, air in faster air out faster will give you more power, start with your most restricted parts such as the exhaust and filter then go into a bigger carb or cams or port and polish.

drop a tooth on the front sprocket, you will lose a very small amount on the top end but how often do you tack out fifth gear. It's only like $10.

Best bag for the buck on most machines is a gearing change, air filter w/ airbox mods, slip-on exhaust, and a re-jet. That's generic advice though--I don't know much about Z400s.

^^^^^^^what he said. that usually the starting point. you will see an improvement. after that, things start getting more involved and more pricey.
