Also would i need to get the bike rejetted if i fit one Thanks to be honest with you(this is only my own personal view) modern super bikes don`t need to be fiddled with if they runnin an pullin clean,never fiddle for fiddles sake it only make them worse!,you can loose a lot of good handy low -midrange power by gettin sucked into top end power trip`s,tune it for how you need it!

henryz Posted July 29, 2009 Share Posted July 29, 2009 I wouldn't put K&Ns on. I bought my FZR 1000 with them already fitted and they have given me so many problems. I can't find a orig airbox and I don't want to rejet as I want to take it back to standard, for now I have had to use axtra filter foam and filter spray to restrict airflow.
