  • Tamper proof bolts - how to remove?

    So there are these two bolts at the bottom of the ignition barrel. I swear they are looking at me the funnily

    Anyhow, i took them into Causeway Kawasaki thinking they probably have the special tool to remove it. 'Was told the only way to remove it is to drill it out, and grab something and pull... and I got lost somewhere along the line there

    So has anyone done this before and how do these bolts / screws work?

    Just thought i'd ask before drillings the whole things out and re-tap the buggers? (alot of work for two bloody screws the size of 2mm, and especially un-nerving when the ignition barrel is made out of plastic )


    PS> it's a Kawasaki GPX250 and no, i am not stealing a bike

        Most ignition bolts are the ones that have the nut part break off at a certain torque leaving a round blank head.

        Usually recessed so you can't cut a slot in them.

        Drill is usually the only option. They are not usually that tight ad come out fairly easy.

        Left hand drill bits will help.

          They look like external TORX (thanks rob), except the corners aint as pointy as the picture shows.

          Here's a pic of the actual thing, excuse the phone camera quality

                on close inspection they probably are not TORX, there are hardly anywhere to grab onto them. It looks like what Hired_Goon has said, some part of the head has been snapped off.

                So how do i go about drilling these out? Drill it out all the way and retap it or would a left hand drill bit turns the thing as it goes in?

                  Yeah, My car is full of tamper-proof fittings. Just have to go buy the right tools and your set.

                    Use a left drill bit as the goon said smaller than the thread size and then use an easy-out to remove it. They normally come out pretty easy.

                        I have taken heaps of these off with cars (job not a theif) The tops are soft try a pin punch and hammer they should come out.

                          Yeah i'd say use a punch and a hammer.

                          just tap a little groove in it somewhere then slowly tap it out with the groove. be warned coz it takes a while.

                            Isn't the Australian refugee manual held together with tamper proof bolts?

                              Try moving it with an automatic centre punch.
