I have the same bike with the Rivco risers and no problems. You need to move the brake block using the small bracket that is provided in the kit, really easy. I had an issue getting the old risers off so I took it to the dealer to finish off, I think it was only a 1/2 hour job so not too bad really.
I am 5'9"" or so and the riding position is greatly improved! You still have to be a bit careful raising the tank but I found it just squeezes past. If you find it a bit close just loosen the pivot (for the tank by the seat end) and slide it out a bit. If you do this to access stuff under the tank, create a reminder for yourself that you removed the pin, I forgot and the tank slipped (full of fuel of course) and caused a bit of chaos %^*#!
