I started the install last night, by myself. Stumbled over a couple things, figured it out. Left side went fine, though I figured that a second set of hands would’ve helped a little at one point. The right side went ok, until I found out that the top bolt hid a washer/spacer that was loose. In trying to hold it just right while positioning the guard, it kept falling, and finally fell to the inside of the engine, where no fingers would reach, though I could at least see it from both sides of the bike. It was too late, so I called it for the night
Got back to it tonight. I used a cut & shaped coat hanger to hook the spacer and got it out. Then I managed to get it placed and the bolt through it with just a couple attempts. Here again was where an extra hand would’ve been nice, but not required. Then I had to put in the thin cross bar between the guards, and found that I really had to have another person to hold one side’s bolt while I turned the other side. Got my daughter to help me out, took all of about 2 minutes.
Overall, working mostly by myself, I’d say the install actually took a bit over an hour. I agree with Curler - having to do it again would probably take about 15 minutes. They look great, too!
Side note, the first thing I want to add to them are some highway pegs. But I sat on the bike and stretched out my legs, and I could actually put my feet right on the guards. Would doing that instead of installing highway pegs be a bad idea? I’ll test it out a little tomorrow on the way to work. I think the pegs are probably a better way to go, but I don’t know for sure.
