kz750g Topic Author Offline User Posts: 2 Thank you received: 0	I connected the timing light on my 1980 KZ750g the way I do on the cars. Used bike battery to connect both leads and tried one of the spark plug ( I do not know which one is the right one!) but nothiong happened. I also connected my jumper battery but no change. Is there something that I am missing? Please advise me. I feel stuck. Without the light connection, I can not check the timing. KZ750g

It depends on the type of timing light. If self powered, one spark plug wire is removed from the plug, the timing light high tension(spark Plug) lead is put between the plug with a special clip like a large battery clip. The other lead of the timing light is connected to the positive battery lead, so when the plug fires the light flashes.

The other type is an inductive timing light that might require plugging in to a electrical outlet for power, but will still need the trigger voltage from the sparkplug to fire and flash the light. It might just clip on to the sparkplug wire with no need to disconnect the wire from the plug.

it's been a few years for me using a timing light as my engines are set and not requiring adjustment except for valve clearances.

If it is inductive then your going to have 3 wires to hook up. Connect the red clamp to the positive post of your battery. The black clamp gets connected to your negative post of your battery. The inductive pickup clamp gets clamped around the thinnest part of a spark plug wire. If you connect it to the spark plug wire boot then your timing light will not work. Once everything is hooked up and your bike is running - just pull the trigger and you should see a pulse. If you do not see a pulse then recheck all three of your connections and try it again. Move the inductive clamp to another spark plug wire if necessary. Hope that helps.
