Electronic Ignition Timing – 00 022 81 (2036) – 6/81

Service-InformatioQn Group: 00 June Bulletin No. Equipment Advice 1981 00 022 81 (2036) – For U.S.A. and Canada Only – Re: 1981 Electronic Ignition System Timing Box. Motorcycles of the 1981 model range incorporate a new ignition system with no conventional contact breaker points. It is a high-tension system featuring a “Hall” tansmitter and mechanical advance by centrifugal force. Basic ignition timing is similar as on 1980 models, but the high voltages mean that the familiar static timing method using a test lamp is unsuitable. For static ignition timing on these models, we have therefore developed a special timer with a high-emitting diode and built-in 9-Volt battery. The strength of the·battery can be confirmed by pressing a button. ….. “·, •.. ··1:-.·.’ .. ·. -[~.,(~_:,,~+tr,;~~fi;:,. • ,:·. ‘..\.’pf.;’:._-_::-.,·,,,._ .
