Mr. W.D.,
Removing the octopus really cleans up your bike. It also deletes some possible vacuum leaks (AND PROBLEMS) inside of your engine. I have never missed mine and my bike runs and starts great.

99 WR, all YZ mods, de-octopused, OEM YZ tank and IMS seat, jetting by Clark/James, got forked by Pro Action, DSP airbox, PB Header, Stroker SX-1 SA, Thumper Rad Guards, Acerbis Hand Guards, WAITING IMPATIENTLY FOR MOAB, boning up on my sheep shearing skills AND knowing Mitch will help me out IN ANY WAY I NEED IT!!
