Install is not hard at all. You have to drill out and retap a couple of the stock windshield mounting holes for the larger hardware, but everything you need and some real good instructions are included. If you can replace your windscreen and can use a tap, you're golden.
I was worried about the cutting because it's pretty beefy steel, but I used my Dremel and one of those reinforced metal cutting wheels, measured and drew a line in pencil, and very slowly and carefully cut with the shelf still in place. Now that I have all that stuff mounted up there, removing the shelf is a pain, so I decided to do it while still installed. I covered the bike up with and old sheet and took my time. That Dremel wheel cut through it like butter. Very easy, just keep your hand steady to make a nice straight cut and be careful not to let the wheel slip out and cut your stock dash. There's plenty of room behind it, but if it slips out you can nick your stock stuff.
Even if you make a mistake, those trim pieces I used will hide it nicely. Plus it makes a sharp metal edge a soft, protected rounded rubber edge. I got the trim at Auto Zone for like $3.
