  • Ignition: inspect plug type, gap, color and deposits
  • Ignition: check plug cap and wire resistance
  • Ignition: test spark with a proper tester
  • Ignition: measure coil primary and secondary resistance where useful
  • Ignition: check coil power supply under load
  • Ignition: scope primary/secondary if available
  • Ignition: inspect crank/cam signal when all cylinders lose spark
  • Ignition: check kill switch and side-stand logic
  • Ignition: avoid open-air spark near fuel vapor
  • Ignition: record cylinder and condition of each plug

How To Use It

Use this checklist before replacing parts. Work from the top down, record the result of each step, and only move to repair decisions when the failed test is clear.

SEO and Research Notes

This original Motomech worksheet is built from common workshop inspection logic: verify the complaint, inspect safety-critical systems first, measure before replacing parts, document the failed test, and finish with a repeatable road-test or service verification.
