It's messy, a pain in the ass, and even if you have one of those window plugs good luck seeing your mark. It is the best thing to use for static timing, and its better/easier than a meter for this purpose.ĭynamic timing is a waste of time on a Harley. On the bike your clip points are going to be one on the case and one of the points spring, then you turn on the key and rotate the crank counter clockwise and watch the bulb as you're on the compression stroke, then check your timing mark alignments, then adjust your points plate advanced or retarded from there. It works for points and electronic ignitions (like Dyna S and so on). What I recommended is a test light, not a timing light. It is slightly more accurate than a light.There is zero confusion from my end. Static timing.įor static timing on the ignition points you can just use a volt ohm meter set on the DC x 1000 scale.
#Motorcycle timing light manual#
Original Factory Workshop Manual for Honda CN250 Motorcycle. Then there are timing lights like that screwdriver looking device that is usedįor the electrical timing of a set of ignition points. The valve timing diagram for a four stroke cycle diesel engine is shown in Figure below. Used when the engine is running by looking at a mark on a flywheel. Some older timing lights require the removal of the spark plug boot in order to attach a direct pickup between the wire's terminal and the centre conductor of the spark plug.There are timing lights that look like a gun. LampInterior LampStrobe LightDaytime Running LightsTaxi LightPilot & Warning. Power for the strobe comes directly from the vehicle's battery. Car Covers & ProtectionCar CoversMotorcycle & Quad CoverTarpaulin & Trailer. Self-contained units used to time automotive engines have an inductive pickup that clamps around the proper spark plug wire and serves as the trigger for the strobe. Timing lights using xenon strobe lamps electronically triggered by the spark provide brighter light, allowing use of the timing lamp under normal shop lighting or daylight conditions.Ī timing light may be a self-contained instrument, but is sometimes combined with a voltmeter, RPM meter, and a dwell angle meter, or may be incorporated into a more comprehensive instrument such as an engine analyser. Simple timing lights may just contain a neon lamp operated by the energy provided by the ignition circuit.
#Motorcycle timing light series#
In few cases an engine is timed off another cylinder, such as the International Harvester V8 engines, which use #8, and the Isuzu 4Z series four-cylinder, which is timed off the #4 cylinder, or the 3 cylinder Saab two-stroke engine which is timed on the middle (#2) cylinder.
On most automotive engines, the timing is set based on the #1 cylinder. The distributor can be rotated slightly until the reference pointer aligns with the specified point on the timing scale.įuel-injected engines, or engines with microprocessor controls may require special procedures to allow basic spark timing to be observed without control effects from the engine computer. A reference pointer is attached to the flywheel housing or other fixed point, and an engraved scale gives the offset between the spark time and the top dead centre position of the piston in the cylinder. some symptoms of a bad timing chain tensioner include: Check Engine Light. The apparent position of the marks, frozen by the stroboscopic effect, indicates the current timing of the spark in relation to piston position. JAGUAR XK II Convertible (X150) 5 Suzuki GSX-R Motorcycle Forums Gixxer 1. The timing light is connected to the ignition circuit and used to illuminate the timing marks on the engine's crankshaft pulley or flywheel, with the engine running. Modern electronically controlled passenger vehicle engines require use of a scan tool to display ignition timing. The black clamp connects to the battery -, the red clamp to +, the green one to the breaker side of the coil (for RPM), the big black clamp in the foreground is an inductive pick-up that clamps around a spark plug wire.Ī timing light is a stroboscope used to dynamically set the ignition timing of an Otto cycle or similar internal combustion engine equipped with a distributor.
