Frequently Asked Questions
What units are marked on spark-plug gap tool 35-0136?
The circular gauge is marked in thousandths of an inch and millimeters so the plug gap can be matched to either form of service specification.
Which spark-plug electrode should be bent when setting the gap?
Bend only the ground electrode with the tool. Do not pry against or place force on the center electrode or its insulator.
Does the gap tool identify the correct spark plug for a Honda CB?
No. First select the correct plug reach, thread, heat range and terminal type, then set its gap to the motorcycle manufacturer's specification.
