You will need 10mm and 12mm wrenches. Start by removing the tool kit on the back of the buddy seat. Remove the two nuts near the top of the Tool Kit compartment. The buddy seat comes off as you pull the seat towards the back. The main seat has two bolts at the back near where the buddy seat tongue hooked under it. Remove those two bolts and the main seat comes off just like the buddy seat. The main gas tank has one bolt at the back and two bolts at the front. take off the bolts and the bushings that pass through the rubber grommets. Before removing the two hoses running from the main tank to the secondary gas tank, you will want to have drained all of the gas from the tanks, which is probably easiest to do by removing the fuel hose that runs from the petcock to the fuel filter and draining into a clean gas can.
The Honda shadow does not have a gas gage it has a lite that comes on when you get to the reserve portion of the tank.
Your toolbox should be, if you have one, behind the seat, in the little pocket with the keyhole in it.
According to the shop manual, the fuel capacity is 12 liters (3.18 gal) with a 2.5 liter (.65 gal) reserve.
Use for example NGK DPR8EIX-9 or NGK DPR8EA-9 spark plugs.

Not really, but it would very much depend on the kid. 700C is adult size wheels, and they fit in adult size frames. If you're of kid age but as tall as some adults then you might be able to use them. Keep in mind that 700C wheels are too big even for some adults.
Well, 700C is a wheel size, also known as 622 mm or 28". But apart from that I can't figure out what the question is.
Yes it should. I've been running 700c tires on my modern 29er wheels without a problem. You could also try looking for 1.5 inch 29er tires.
It's best not to use tire sizes in inches, as there are often several different sizes in the same inch designation. Safest is the ETRTO size in millimeters, where 700C = ETRTO 622 mm. If you insist, 700C will usually be a 28" - but there are at least two sizes starting with 28".
Almost 100% definitely not.
C as in 700C is a leftover from an old french sizing system. Doesn't say much today. Sheldonbrown.com has nice writeup about tire sizing. It's better to stick with the ETRTO marking of diameter (in mm) and width (in mm). A 700C tire will be 622 x 23-38 mm. 23 mm width for a road bike, 38 mm for a hybrid.
