you by a jet kit when you want to rejet your bike !
if you put a pipe its probably not neccesary but if you put a filter with your pipe you will have to rejet because more aire is coming in and you have more flow cause of the pipe!!

you may need a re-jet after you add a full sysytem.A jet kit will offer you new a new needle jet (different profile from stock) a few different pilot jets and a few different main jets. The drawback to that is the jets are not always numbered the same ans stock mikuni or Keihin. So you may just need to re-jet and adjust your air screw. buy a shop manual for your bike and read through the carb section so you understand how it works before you tear into it. Also a Dial -A-Jet system works very well for the 400ex as well
check out the Thunder Products web siye for info on that.
