Changing my bars back to clip-ons, I needed to disassemble the twist grip to re-route the cable and when I went in to pull the cable out of the grip "scroll, circle, thingie" I noticed a second set of holes the cable end could sit in.
These are further out toward the edge of the white plastic circle the cable end anchors in.
I put the cable end in there and damn if it doesn't have faster action!
Well, of course it would being out further but is it designed that way to give you a choice?
