The following excerpt is an example of the content found in the electrical chapter of this 1978-1980 Kawasaki KZ650 Motorcycle Service Repair Manual.
A wiring diagram of one half of the KZ650 ignition system is shown in Fig. K12. The other half is identical, and works as follows. The KZ650 battery supplies the current for the primary circuit, which includes the contact breaker points, capacitor, and the primary winding of the ignition coil. When the points suddenly open with the ignition switch turned on, a surge of electrons is produced in the secondary circuit, which includes the ignition coil secondary winding and the two spark plugs. The two sets of points and two coils take the place of a distributor, which is left out to increase the reliability of the system. Each set of points fires two spark plugs every time the two pistons rise, that is, once every 360° of crankshaft rotation. Since the two sets of points (and the two sets of pistons) are 180° out of phase, plugs 2 and 3 fire 180° of crankshaft rotation after plugs 1 and 4 fire, and vice versa. For this system to function properly, all ignition parts must be in good order, the ignition timing correctly set, the ignition and engine stop switches not shorted, and all wiring in good condition (no shorts or breaks, and no loose or corroded connections). Ordinarily in a 4-strokc engine, a spark jumps across the spark plug electrodes only every other time that the piston for that spark plug rises (once every 720° of crankshaft rotation). This is because between each compression stroke, in which a fuel/air mixture ready for combustion is in the cylinder, there is an exhaust stroke, in which the piston rises only to push out the burned gases. However, even if a spark does jump across the electrodes during the exhaust stroke, there is no effect since there is no compression and no fuel to burn. Therefore, to eliminate any need for a distributor (thus simplifying the system and making it more reliable), the system is constructed so that both spark plugs fire every time both pistons rise (once every 360° of crankshaft rotation) although one piston is on the compression stroke and the other on the exhaust stroke.

SPECIAL NOTICE REGARDING COPYRIGHT PROTECTED MATERIALS
Motocom, Inc., d/b/a RepairManual offers access to a diverse repair manual library. In-as-much as our roots are grounded in motorcycles and motorcycling, we offer repair manuals relating to cars, trucks, vans, all terrain vehicles, snowmobiles, tractors, and personal watercraft.
Two broad classes of repair manuals are offered by RepairManual on Ebay, namely, reproductions of original repair manuals, and original repair manuals, i.e., titles of others, which we purchase new or used from OEMs and publishers via their authorized distribution channels and pass on to you our customers. In connection to our content, we strive to locate, secure and clear the titles we make available to you directly as reproductions.
As to the former, namely our reproduction titles, we offer copies of public domain content, more particularly, titles published prior to 1989 and without active copyright. For decades, an outstanding feature distinguishing United States copyright law from that of the rest of the world has been an emphasis on formalities, among other things a requirement that the public be given formal notice of every work in which copyright is claimed. This facet of the law has origins in the original Copyright Act of 1790. and has remained in the successive Act revisions of 1831,1870, 1909,1976 (effective 1978). Many of the formalities under the 1909 and 1976 Acts have been lifted with the accession of the United States to the Berne Convention, via passage of the Berne Convention Implementation Act of 1988.
Before 1978, federal copyright was generally secured by the act of publication with notice of copyright, assuming compliance with all other statutory conditions. United States works in the public domain on January 1, 1978 remained in the public domain under the 1976 Copyright Act. As of March 1, 1989, the effective date of the Berne Convention Implementation Act, copyright notice, among other things, was prospectively eliminated as a condition to copyright protection. However, where a copyright notice is required, essentially for all published Pre-Beme content, and its omission is not excused, the legal consequence is to inject the work into the public domain.
In connection to our business, namely the offering of manuals and parts, we by necessity make use of trademarks and/or trade dress of others to describe the items we offer. In doing so, no representation of affiliation, association or the like is intended, unless otherwise stated. Moreover, we are in fact owners of intellectual property, property that is a valuable asset to our business. If you are a copyright owner we ask that you please contact Mr. Lenard Nelson at 1-828-284-0944 (Monday - Friday / 9am - 5pm EST) to answer any questions or remedy any trademark or copyright concerns. Thank you.
