Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
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 CDI box.
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, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

G'day egdbcs . Ok.now lets see.You say good spark,so i'm presuming you are doing the old sight test.Try bending the arm on a know good sparkplug about 5-6mm,earth the plug and kick'er in the guts(crank it over)Be very carefull , high voltage danger.If there's still a good spark it's safe to say that there will also be a good spark under pressure in the combustion chamber,speaking of which you should also do a compression test,anything over 100psi should be ok. as i'm not to sure of the extent of the re-build,hopefully the valves were lapped and checked for straight and true and valve seals replaced,if you notice oil on the tip of the spark plug you could have a leaking valve seal or oil seal .Try putting a small amount of fuel directly into the combustion chamber ,tighten up the spark plug ,install the plug cap and.......Yeah ..You guessed it ..."kicker in the guts".If all the abouve are correct and true it should fire up.If it runs for 5-10 seconds then stops you've got some sort of fuel starvation problem , could be dirt in the carb,blocked idle jet ,or air passage or even the needle could have come off it's clip,believe me with an old bike like yours anything could be worn and loose inside that carby.The only other thing to consider is the timing.There may be a good spark but is it happening at the right time inside the engine???. I'll leave it all in your capable hands EGDBCS.Hope this helps to solving your worries. Chow for now......Tilleydog..

Check the battery should be 12V or more , Then check the coils the connections are under the gas tank make sure they are securely connected.
What kind of fuse box do you have? The glass fuses? Or did you replace the fuse box. If it is the glass fuses you need to replace with a new fuse box.
Check the kill switch and the side stand switch.
Check the coils too..

SOURCE: cant get a spark from yamaha kodiak 400

I did one about a year ago & it was the pulser coil(black plastic pickup next to magneto behind L/H engine cover) but

  1. I'm not suggesting that this is definatly the fault
  2. But id check it first
  3. I havent got the spec for it but got it from my Yamaha dealer easy enough(you'll need the wire colours as well)
  4. contact me back if you can't get them and i'll see what I can do(it'll be another week before I can get it as my phone is shot! blew the line clean out of the wall in a storm a couple of weeks ago)
Hope this helps

SOURCE: weak spark 1973 yamaha rt1 i don't see a spark

Problem could be a few different things. Not sure on all the ignition parts on that bike, but could be a bad sparkplug cap, wire, coil or magneto. My recommendation would be to first take the spark plug cap off. Trim a bit off the wire and put the cap back on. Over time spark plug caps move quite a bit and wear out the wire inside cause a weak connection.

Thanks

YAMAHA YZF R1 2000 NOT STARTING


A little more information is needed here. Is the bike turning over? Is the starter motor turning the engine over but not starting? Is it sputtering or coughing or backfiring?

Was it running and then just stopped? has it been sitting for a while and now won't start?

Engines need fuel, air, compression and spark to fire. Try the following. Try to start it and then:

1. pull the spark plugs. Are they wet? can you smell gas? If not you probably are not getting fuel to the engine for it to start. This bike probably has fuel injection. On many FI bikes, when you turn it on you can hear the fuel pump turn on. do you hear that? Look at the fuse box and see if you have a blown fuse for any critical functions such as fuel pump, ignition, etc.

How do the spark plugs look? Are they corroded and black and burned looking? Fouled spark plugs. Try replacing them. If they are whitish and look as if the metal as eroded away your engine is running lean and you need new plugs but also need to address running too lean or you will burn up your engine.

2. If spark plugs are wet you are getting gas. hold the base of the spark plug against metal such as the engine and press the starter. You should see a spark on the plug if it is properly grounded. If you don't see a spark then either your plugs are bad or you aren't getting spark due to a dead battery or a problem between the battery and the spark plug such as fuse box or an issue with chip that controls the engine.

3. How old is the battery? If you are having battery issues you probably can't run the starter but you might be having issues there as well.

4. If the bike is sputtering and backfiring it is probably a timing issue. I don't know your model of bike but I am pretty sure the timing is controlled by a chip. That may have issues or again, maybe a fuse that controls elements of the ignition system has blown. Are there any wires that have broken or have exposed metal that could be shorting? Any of the leads to the FI system come undone?

Hi, Dave00373 and the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, needs to be 12.5 volts or better and be able to pass a "LOAD" test, your battery may show 12.5 volts but has little or zero amps and must be replaced.
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 CDI 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

I have a 2001 660 Raptor. Thought it had dead gas in it and hadnt been started in about 2 years. Drained the gas, put in fresh gas and it sputtered and backfired. rebuilt the carburator and does the...


Hows the oil in it? also i would suggest spark plug sitting that long with gas inside the tank isnt good for any bike but it was good to drain. If its not spark plug check all basic engine problems than maby bring to mechanic it may need rebuilt.

Ignition turns over but just wont crank, Carburetor was recently rebuilt!


If the engine turns over are you are definately getting fuel then spray a small shot of ether into the intake. You will know for sure if you are getting spark if the ether ignites. If it ignites and you know you have feul gettin there then you have Spark, fuel, now you need to check compression to see if it has enough to keep running.
