You could just unplug them and tie up the loose ends but if you wanted to pull them and put the plugs in (recommended) you can pick up some plugs at NAPA.
Here is a link Glider posted about that.
02 Sensor Plugs - Harley Davidson Community
rydahog; want to make sure we're on the same page...you want to plug the O2 ports/bungs in your header pipe, or plug the O2 sensor wire connector plug? If it's the O2 sensor wire plug - need to get the caps from Dobeck to make system function properly. If it's the O2 bungs on pipe - get the ones from Napa & they remove/install with open end wrench (can't remember exact size). Enjoy!
wow, now your stretching my old feeble memory banks,,
i thought with the chat i had with dobeck rep, that he was going to include caps i guess for o2's ? but not specified removal of sensors or plugging end of wires of o2's? so i guess the easier was is to see if they will send me caps??
OR...haha jsut take out 02's from header and use napa part? suggestions are always needed..thanks ryd
