The Ram-mount for the Reservoir goes over your existing cover. You get replacement screws and a set of bushing shims that hold the ram-mount plate just above the original reservoir cover. You don't take off or open the existing reservoir.
I've been very pleased with the system. I use a droid phone for gps and communication (Uclear helmet Bluetooth). The phone doesn't vibrate much (done about 3K miles with the mounts since December '15) and I've never had to tighten any of the system up since initial install (I've checked for tightness but nothings loosened).
No those aren't heated grips- just some "Grab On Grips Grip Cover - Fits From 1.25in. to 1.45in. OD - 5in.L, Color: Black MC402" through Amazon to increase the grip diameter some.
