I need to replace my grips. Have Pro-Taper ATV High bars with Suzuki hand guards. Made the usual modification to use fuel line as the expander on the bar ends when I did the original install. Now I'm trying to get the bar ends out. Know not to undo the screw all the way. Only did it about half an inch and the screw moves in and out so I think I'm good there. But the outer expander is stuck solid (#9 in the service manual diagram). Have been wiggling and pulling but neither side will budge. And advice on how to get them out?
