Is the kill switch on? Check the side stand kill switch if you have one. They sometimes go bad. Disconnect the handlebar kill switch. Does it start now? Also check the key switch. A switch can go bad as well.

Before going to the CDI system go ahead and check the kill switches including the side stand switch, with an Ohmmeter. How good is the battery? Check the fuses. Check the wiring harness. Are all wires clean and with a solid connection? Any abraded wires? Check the operation of the ignition switch with a volt ohmmeter. Is the bike in neutral and the neutral light is lit up?

You can download a free PDF factory service manual by going to the website below >

The manual should tell you in detail how to test the CDI and other electrics.

SOURCE: 04 yfz 450 wont start with electrical start

i have a 04 yfz 450 quad. the compression ratio like yours is extremely high. ive had my battery go bad and found that another battery other than factory would turn over the engine, but would not start. i paid the 100 dollars for the factory battery and it fired right up. because of the high compression you need a high cranking battery.

SOURCE: no spark put on a new cdi box coil good and a new

hi,sounds to me like your cdi pickup unit has failed,i am not 100% certain but this will be located on the end of the crankshaft behind one of the enginecovers,there could be two other possibilities,motox bikes are notorious for breaking wires so check the wiring from the cdi sender unit to the cdi box and the coil,also check your "off"button it may be stuck in the "kill" position..hope this helps..cheers ian

SOURCE: i have a cpi oliver

I possibly have the same problem. I have narrowed it down to a fuel (lack of) problem. If you remove the seat and take off the vacum tube leading to the fuel tank cut off valve ( on the bottom of the fuel tank) you will be able to squirt a little fuel directly into the intake manifold,replace the tube and hopefully it will start instantly.no dought it will then stop repeat the process several times.
I suspect there is an electric soleniod system to deliver fuel on startup, I have dismantled the carb and am fairly sure the problem is with the electric needle system on the rear of the carb.
Hope it helps

1400 intruder no fire to the coil pack front cylinder coil is good stater is OK fuses good new pulse good .is the cdi out


Hi, Earl 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.

Can't Start 1981 Yamaha SR250


find a running sr 250 and swop his cdi unit with yours if the bike runs, fine. if not put his cdi back in and try again. if the good bike now starts it will indicate that your cdi is faulty. the cdi is located under the tank inside the frame. don't buy a second hand cdi unless you can test it on a working bike. they are very expensive and you don't want to buy a dud

Hi.
It's either your coil or CDI thats at fault.
Download yourself a copy of the service manual from the internet and measure the coil resistance values that are quoted in the manual.(how and where to measure is usually shown in all good manuals)
If these are correct then its most likely your CDI.
Your Honda dealership should be able to test this for you, but this may cost as much as a second hand CDI.
The CDI on the XR200 is the same as a lot of models eg. cb125, cd125 .
You will find quite a few on ebay , both new and second hand , make sure you get the same model as already in use (number should be on the CDI)
good luck

No spark at spark plugs so wont fire new battery all connections and grounds seem good was sitting for 3 months and ran at that time someone had turned on key and ran down the bat. so replaced but now have...


Check the coils first, leaving the key on may have burnt out part of your ignition system.
Easiest way to check coils is to pull one lead off, plug a spark plug into it. Run a hot wire from the positive side of the battery to the coil ( Do Not Plug it in!!) . If you flash the wire on and off the power side of the coil it should make a spark jump across the sparkplug ( don't forget to earth the base of the plug.)
If the coils are ok, see if you can borrow a CDI unit to try in your bike ( it is good to have mates with the same brand of bike )
Don't forget to check all fuses first and make sure the "Kill Switch" on the handlebars is on.
Happy fault finding.

Cant get a spark from ht leads on cb250 motor bike


Be CERTAIN the battery is good. Are all fuses good? Try brand new spark plugs. Disconnect the kill switch on the handle bar. Check the side stand kill switch for proper operation. Have the shop check the CDI ignition.

Get a BRAND NEW plug and recheck for spark. Be sure plug is grounded to engine. By the way, FTjoe (above) has some very good questions. The sator is not involved here. The dealer can check the CDI usually for free.
