I just installed my Moose Handguards- they're pretty straightforward, actually.
However, be careful, as it looks like the bar attachment has changed. Instead of a single curved arm that you can turn both ways in order to get the brake line or clutch cable out of the way, mine came with straight pillars with small holes in them. On the clutch side, I had to drill it out, and run my clutch cable through it in order to make it work. I'm a little concerned about premature wear on the cable, but I think I got it tweaked so it's close enough to in-line to not make a terrible difference. I will keep an eye on it.
On the brake side, the brake line comes stupidly close to the bar attachment, and only by turning the entire master cylinder assembly a few degrees did I get it so everything lines up. Both the levers are angled down a few degrees to get everything to fit, and with the bike straight up, it's fairly comfortable and the handguards are straight forward.
Bar ends went on flawlessly- take the screw loose, pull the assembly out a few CM, then undo the screw and take the weight off. When reassembling, torque it down until it's tight- even though the screw is smaller diameter than the hole in the Moose guard, it's tight enough to not make a difference- no vibes or loose anything. Way easier than fabbing up something to work with the Moose equipment they send or doing without the ends.
