Hope your adventure in picking up your bike today, or hopefully at least by tomorrow, went well.
Lang is right about the fork oil. I totally forgot about that one! He's also right about the VT700 being sleeved down from the original 750. If you want a bit of fun doing a treasure hunt on Google, look for the reason why the Shadow was a 750 in 1983, a 700 in 1984-87 and then up to 800 in 1988. I'll give you a hint: "Think Harley!"
There's one more very
important thing that I forgot to add to the list: Remove the dashboard light panel (two screws on the sides of it, and it pops right out) and make sure all of the bulbs in there work! When I picked mine up two of them were burned out. The tail light indicator bulb was burned, which is no big deal at all, but the fuel warning light was burned out also! This model does not have a fuel reserve. When the fuel runs low, it lights the lamp on the dash to tell you to fill up. I was riding my bike home from Maine (5 hour ride) on the day I got it and I thought that I was getting amazing gas mileage until it died on me because the fuel light was burned out!
Luckily, my brother was following me in his car, and we brought a gas can for just such a possibility. But check all the lights!
Also, when you get it, turn the ignition on, and see which lamps light. Several of them light for a few seconds and then go out when you first turn on the ignition, just so you can check the bulbs. Familiarize yourself which which lamps light, and get in the habit of looking at them every time. It will save you grief in the future!
Also, if you have a paved driveway, do your work there. I don't, so I do all of my work on the front lawn, and I can't tell you how many hours I've wasted looking for small bolts and nuts and things that have fallen into the grass. One of these days, I'm going to get a sheet of cheap plywood, and roll the bike onto that when I'm working, but I haven't done that yet.
