Since you are new to riding and the Honda 400s a few things you may find interesting. The 400 motor is a 360 degree motor. This means both pistons go up and down at the same time. Both spark plugs fire at the same time. One on the compression stroke the other on an open exhaust valve. Some call it a wasted spark motor. It has a capacitor discharge ignition system. The ignition system is flywheel to stator to CDI to coils to plugs. It will run without the battery. The battery is for the starter and lights. As I suggested read the manual before doing anything.

For parts I go to my search engine and type in the year , make , model of the bike, with the name of the part you are looking for and the part number . If its on the net it will show up. you can find part numbers on the above named places .I do this when having trouble finding parts.

Have fun

Nice looking bike for an original. IMHO I would spend the summer riding and enjoying the bike and take the time to learn the bike and decide what you want to do. Look for parts that you need or want. Buy or download a Honda full service manual and read it cover to cover .Spend the time to learn the bike before doing anything. Good luck and happy riding.
