I have a gen 3 z1000 and took out the insert by using a dremel to to the welds and then later realizing that kawasaki also put a tac weld on the inside. You must take off the controls to get at the hold where the tac weld is. Used a drill and drilled until i broke up the weld enough and pulled the insert out. I know its been a few years since this question was up but i hope this helps anyone else looking because i know i could never find anything. check out my youtube video for a visual representation.On 2015 z1000, how exactly do I remove the inserts that are in the handle bar after I remove the bar ends?
I did a search and couldn't quite find the answer.
