Takes special equipment to test the CDI ... does your bike start? run? if not ... there is that possibility that who ever told you it is bad is correct.

How to replace thermostat on 1980 honda cx 500 silverwing motercycle


Drain the radiator and remove the fuel tank. The thermostat is in a housing between the two cylinder heads. Two 6 mm bolts(10 mm wrench)hold the stat cover down. Replace the o-ring and thermostat together. Thermostat can be tested by placing in a pot of water on the stove, heat the water, and check opening temperature with candy thermometer. I had a friend that removed his and never put it back. It just took longer for the bike to warm up. good for warm climates but not cold climates.

1983 Honda CX 500 B no spark


Hi, Roxsaund and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

1980 Honda Cm400a No spark


Hi and welcome to FixYa,

Bypassing the kill switch means removing the connection of the black / white wire either at the emergency stop switch (kill/run), ignition switch or preferably at the CDI connector.

Additionally, you can try:
  • start with the side stand up;
  • check/wiggle the 6 wires coming from the stator going to the CDI.

Would appreciate a postback on results / updates.

Good luck and thank you for using FixYa.
