After first trying to use the epoxy as a lube, a just took a look at how much the knurled end was taking off and deemed it was okay to force it on since nothing eletrical was showing. I filed the handle bar as best I could with a the sharp edge of a chisel (wouldn't recommend, but it was all I had), and then pounded the thing on. I had some plastic shavings, but not enough to keep me concerned. One thing I would suggest is to use something flat like a block off wood--or use a mallet--too pound on the grip with. I had a finishing hammer, and while using it lightly, there is a outer portion of rubber that serves as a spacer that likes to tear away. Its nothing consequential if it does, and you can't noticed mine since I have hand-guards on anyways, but just cautioning you.
Hopefully that process enlightens you, I had to quickly come to solution to the kurnled handlebar with what tools a I had, and so explains the medieval methods of getting the grip on, which I though prior to starting would just slip on.
