What kind of spark plug does a Honda CB450 use?
Blue wire goes to the points, black is to 12 volt+. The spark plug boots thread into the end of the spark plug wire with a threaded connector. Make sure that terminal is threading securely into the wire itself, and not off to the side into the insulation. *Note that our “regular” spark plug boot can work on the Honda CB450/500T but it will be snug.
Is the ignition coil on a Honda working?
If the ignition coils on your Honda are working fine but you still see some timing issues, try one of our ignition rebuild kits, as well as a new set of spark plugs to return to top performance. Installation Tip: Disconnect the negative terminal on your bike’s battery before you start working to avoid shorts and other bad stuff.

Why are my Honda CB 750 choppers not working?
If you get a reading with no wires and no reading without, then the wires are most likely your problem. INSULATION BREAKDOWN These coils have a solid metal core running through them. It is used solely for mounting. It is not a ground. Sometimes the insulation inside the coils starts to break down and the coil will short to the metal core.
How many spark plugs does a Honda CB750 need?
Use one test lead in each of the spark plug wire connectors. You may have to wiggle them around to get them to a spot where you are getting a reading. Depending on the coil you should get a reading of 5Kohms to 20Kohms. I don’t have a manual with me so I will edit later for the actual cb750 specs. If you get no reading, the coil is bad.
What should primary resistance be on Honda CB 750?
PRIMARY RESISTANCE Set the multimeter to measure ohms. Use one test lead on each of the small terminals that attach to the wiring harness. If using stock coils, you should get a reading of approx 5 ohms. If using DOHC or most aftermarket “hot” coils the reading should be about 3 ohms.

What should the electrical reading be on a Honda CB 750?
This test can also be performed with the plug wires and caps in place. Due to the extra resistance though you should get a reading between 10Kohm to 50Kohms depending on the coil, wires and caps. If this is done first, and there is no reading, do the test without the wires.
