Yes similar principle, it stops and starts the fuel from flowing and more importantly maintains a constant head of fuel available for the main jet, if the pressure/level varies too much then too much or too little fuel will be sucked in.

The engine will still run with air box and exhaust mods but may well be weak or not ideally setup which may cause heat damage. or running issues, flat spots etc. So tuning is advisable and a dynojet kit with modified jets and needle will ensure more accurate fuel control and better performance all round.
