1978 Honda CB750A · Ignition Parts Buying guide

Identify each contact point and the coil package

The contact points are separate right- and left-side pieces with different cylinder applications. The featured coil assembly supplies a pair on brackets; condensers and spark plugs retain their own listing quantities.

Keep removed points identified by side

Retain each point’s side identification while assessing the ignition. Compare the reference and listed cylinder pair before ordering the replacement. Use the correct service procedure for setting up the fitted system; the product’s side designation is not an ignition-timing specification.

Choose service parts for the system actually fitted

Inspect the existing ignition before assembling the order. A points-based service and an electronic-conversion repair can call for different components, even on the same motorcycle. Match the chosen parts to that system’s documented requirements.

Common questions

How do the two contact-point products differ?

The right-side listing supplies one contact point for cylinders 2 and 3. The left-side listing supplies one for cylinders 1 and 4. Match the existing point’s position and the stated application before choosing either separate product.

Why does the coil listing give both 4.3 ohms and 15,000 ohms?

They are the listed primary and secondary winding resistances, respectively. Dynatek’s coil-testing guidance distinguishes primary readings at the screw terminals from secondary readings at the high-voltage outputs. Compare the correct winding’s specification when assessing a coil; the larger secondary figure is not an alternative primary reading.

Should I add anti-seize to the order for the NGK D8EA plugs?

NGK advises against anti-seize or lubricant on its plated spark-plug threads. The plating helps resist corrosion and release the plug, while added lubricant changes tightening behavior. Follow the instructions supplied with the selected plugs and the applicable service specification rather than adding anti-seize as a routine extra.
