2.5 Ignition coil
2.5.1 Disassembly
Remove the body guard.
Remove the spark plug cap.
Remove the primary lead of the ignition coil.
Remove the fixing bolts and then the ignition coil.
Install the ignition coil in reverse order.
* Note
Install the primary coil with black/white terminal.
2.5.2 Check the primary coil
Measure impedance between terminals of the primary coil.
Standard: 0.6Ω±10％（20）
It shows good if the impedance is within the range of standard
values.
Replace the primary coil if the impedance shows ∞ which (点火线图：Ignition Coil Drawing)
indicates that the coil breaks.
