I have searched the forum and cannot find anything, probably because its a stupid question. I bought a throttle rocker from kuryaykin. My grips are hd custom. They look a bit like the kuryaykin iso's but not exactly. I popped the end cap off the throttle side grip but the rubber insert has no small screw set like the instructions say and when I try to pry it off it seems that it isn't a cap but an insert. It won't come out and forcing it seems a really bad idea. This would be a stupid thing to have to pay someone for. Any thoughts?

 

Did you buy the universal throttle boss, or the ISO throttle boss? The ISO only fits ISO grips.
