Highway bars aren't particularly a challenge even for the somewhat mechanically challenged; but a floor jack or other suitable jack, preferably a bike lift should be available. The long bolt across the top of the engine (engine mounting bolt) will have to be withdrawn. You'll have to support the front of the engine. You want to squarely stand the bike up with the bike lift without actually lifting the bike off the ground. On second thought, you probably want a mechanic to do it. It takes about an hour to put on front and back bars (dealer hours).
A query here or elsewhere may be advisable about OEM bars versus Rivco bars. At one time (I vaguely recall they've since improved them) the OEM bars had a bit too much forward flex when stretching out on the highway pegs. I believe it was a Pig9r post that gave light on the newer OEM bars having stronger flanges for affixing to the engine. The OEM bars extend outside the radiator shroud and floor boards (as they should IMO) a bit more than Rivco's offering and OEMs are considerably more vertical at the outer perspective while the Rivco's canted inward toward the lower perspective.
Additionally, affixing running lights to the highway bars onto the OEM bars, IMO, is more visually appealing with the bars more vertical and outside the radiator shroud.
But to each his own.
