I'm actually in the midst of doing mine right now. I spent the day removing body panels, cowling struts, suction valves and a ton of plugs and connectors. I had a deer destroy the body a couple years ago, so I'm pretty familiar with getting that on and off. I am curious though. At 47,000 miles, is this your first adjustment? Mine is at 52,000, and this is my first time under the cover. She still runs great, so I'm hoping it's not too bad. If you can get this done for $750, I'd say its a steel. I was quoted $1200, but I still had inner cowling panels to replace from the deer strike, not to mention some dyna-mat and foam body gaskets I hadn't replaced yet. (No, that stuff don't come with replacement panels. Nor do any of the fasteners.) Live and learn....
I can see mine going into, at least, a third day. Besides the extra body panels, I've got plugs, gaskets, and cover O-rings to do. Not to mention I found the suction valve hoses need replacing, and I figure to do the antifreeze, oil and filter while I'm at it. I have learned that I need a 5mm 1/4" allen socket. Doing those suction reed covers with a standard allen wrench is a nightmare.
I do have to say these things are an amazing machine. I'm on my 6th year, and other that the deer damage, all I've done is farkle it up, change the oil regularly and feed it tires, and a couple sets of brake pads. Oh yea, last year I replaced the fluid in the front brakes, and the battery. Not because it was bad, but because it was 5 years old. She's never failed to get me home, even after t-boning a deer in NY.
