I'm working on installing the Kaoko throttle lock and I'm stuck on trying to remove the right-hand throttle inner handle bar insert. The directions say to use two small screwdrivers to prize in the two spring tabs towards each other and then simultaneously pull out the insert. I can slightly prize the two spring tabs in but can't get the insert to pull out. With a plier on the outside of the insert I can rotate it so it doesn't seem like it is glued in? I've attached two pictures. One showing the top spring clip and the second a picture I got off this forum, showing a picture of the insert. Any ideas? Thank You.
