The only challenge I had was installing the compressor under the battery box. Maybe the newer bikes are different where the comp goes other than that the rest was easy.
They're different now, Terry. The compressor is on a flat bracket that mounts flush between the frame members, just in back of the pan. MUCH easier to do than the old under the battery box...that made me say a bunch of cuss words when I did that back in '06.
OP...the only thing I can suggest is to be sure and NOT extend the shocks with your hands, nor compress them. If you're on a jack, mount the bottom of the shock with the rear tire fully off the ground, then slowly lower it until the top holes line up...it's a little touchy, but not that difficult. Then raise it back up and run the air lines, being careful not to get them close to the hot stuff...have some black wire ties on hand. If you're also mounting the chrome switch on the handlebar, it can go on either side...you just have to connect the wires where the top button is up and the bottom is down. If you decide to put it on the right side, that just means swapping two wires where they connect to the leads coming off the compressor motor. Use some dilectic (sp?) grease on the connections and make sure they are seated well into the connectors, then wire tie them right above and below the connectors. If you can raise the tank, run the switch wires under it, along the backbone of the frame...OR, you can run them under the tank console (easier). Putting the switch on the left side is a bit easier to use on the fly. If you're going to try and run the switch wires internally on the bars, that's a whole 'nother ball game. It can be done, it's just a lot more aggravating. If you go that route, let me know, and I'll have another tip or two.
Oh yea...be sure and use Blue Loctite on the shock bolts, and TQ them down good.
