I would, inspect, and if needed clean and gap the plug, if it's really shitty replace it. look over the fuel and oil lines, if the oil line needs replacing, you may need to bleed the system, not 100% on this, but if you have to you must. a little fogging oil in cyl and she should go, it's a Honda after all, these are awesome bikes! Get it registered, and consider yourself fortunate if it is titled in WI, they are kinda a pita re: titles. Vacuum petcock may need replacing, I would not get into the carb unless it will not run/hold an idle, look in the air-box for bugs etc, clean replace filter if it looks bad, and poke something up the exhaust to see it is clear. NEW battery. AGM if possible. If your kid is not into it and you don't want to ride it, contact myself or Randy, we will arm wrestle for the chance to buy it! :) Best of luck getting her going, prob not as hard as you may think! If there is any gas in it dump it and replace with fresh. (edited)
