SOURCE: honda cbr 400 rr starting problem

i could not find a schematic of a 96 cbr400rr, so guessing this bike is not from the USA. however, there should be a master fuse near the battery on the positive side mounted to the battery box somewhere. i would check this fuse first to see if its burned out.

also, is battery fully charged? might have to top charge the battery to get good juice if its old (>3 years) and been sitting for a bit.

good luck.

SOURCE: Honda with no spark

Check the fuses. Next, check for spark but with a new spark plugs. How good is the battery? Try a jump from your car battery. Is the kill switch on? Does the side stand have a kill switch? Is it working properly? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Be sure you have power coming out of the switch.

Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop.

Please rate this answer. Thanks Dan!

SOURCE: 1981 honda goldwing wont start

while trying to start an engine, and only the solenoid clicks, there are these 3 things- no juice from the battery, starter corroded contacts(the big cables) or starter is shot. so first make sure the battery is charged, next make sure the cable mounts from battery to starter are clean(no rust), if that is all good and doesnt start , remove starter and have it tested.

Hi, your plug number for an NGK plug is D8ESL As far as the plug socket size it is a 13/16 deep well socket. The gap should be set at .07-.08mm.

1979 Hondamatic CM 400 A no spark


Hi, Anonymous 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 pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Tilt sensor needs a reset.
11. Security alarm failing to disarm needs reset

Hello, i have a 1980 Honda Cm 400t. it hasn't been started in a while, but was said to have been running very well when it did. Even cleaned the carbs for giggles and they looked spotless. anyway,...


The old honda twins did suffer with ignition problems,( ofcourse they all run well at one time) CDI units and Alternators although checked out were often the cause of failure to spark, assuming you have checked all the obviouse, engine cutout in centre position for running, next remove 1 spark plug cap leaving the other connected to the inserted plug, holding the bare leade aprox 2mm away from the cylinder head, crank the engine over and check for a spark, if ness touch the lead on the head, if a very weak spark is visible then the ignition side of the alternator has failed, often the ignition coil can fail when first used after a long time standing

My 1981 yamaha 400 special will start, (sometimes) but will not stay running for more than a minute or so, any ideas?


Is there gas coming from the gas line? Its sounds like you need a new spark plug maybe even a carburetor cleaning. Thats my guess.
