20 Most Recent 1980 kawasaki KE 125 Questions & Answers


Hi, Jerry464 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 the 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. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

Hi,
From what you describe it sounds like the big end bearings to me.
Gearbox problems tend to be slipping in and out of gear or difficulty selecting a gear. Be careful doing this but if you place the blade of a large screw driver against the engine casing and place your ear against the handle, you can use the screwdriver as a stethoscope and listen for engine noises. It may give you an indication where the noise is coming from. Get someone to hold the bike steady with the engine running as you put the blade of the screwdriver against the engine casing and the handle close to your ear. Watch out for the hot exhaust in particular. The longer the screwdriver the better. Do take care doing this but it's an old mechanics trick to trace noise problems.
Good luck, I hope you get it sorted.

Yes, there is a lighting coil that only powers the headlight when the engine is running, all other lights/indicators can be run off the battery when not running.

A new carb at Babbitt's is $209.23. Having a shop clean the existing carb would probably be $40 if you take the carb to them. Be aware that most shops will not work on bikes over 10 years old. Call a shop and ask for sure. The problem with buying an older bike is parts availability. Kawasaki parts are easier found than the other Japanese bikes. Go to the site below for parts. Please rate my answer.

Hi, Jacksonsc107 the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

Hi, Boettinger6 engine "BOG" is mainly caused by a rich air and lean fuel condition but it can also be caused by a lean air and rich fuel condition this situation rarely occurs and is only caused by the misinformed weekend warrior that owns a toolbox. If the bike has been sitting for months or years you will have to completely disassemble the carburetor and submerge the parts (except rubber parts) in "Carburetor Dip" It usually comes in a gallon bucket with a wire mesh basket that can be purchased at any automotive store. If it is not the above scenario then the following explanation will apply.
The more you open your throttle the more vacuum you are creating in your carburetor venturi and your intake manifold. When you are operating at higher RPM any unmetered air that leaks into your system can become more obvious.
Unmetered air is air that is getting into your system after the fuel has been delivered. If you have unmetered air getting into your system between the butterfly/slide of the carburetor and the cylinder head this will create a lean condition.
All of the rubber components of the fuel system like vacuum hoses and intake manifold that you mount the carburetor to are made of rubber. If none of these components have been changed they are more than likely highly degraded and probably cracked in places to allow unwanted-unmetered-contaminated air into the combustion chamber. Check all of your vacuum lines and vacuum plugs for carburetor synchronization. The vacuum plugs are in the head just after the rubber intake manifolds. The petcock has a vacuum line as well as part of the emission system.
1. Check the intake manifold for fissures.
2. Ensure the bands used to tighten the manifolds down on the intake are secure and have not bound up the manifold.
3. Make sure air box fittings are not warped and fit completely over the carburetor.
4. For 2 strokes make sure the power valve is adjusted properly.
Your airbox is metering air and is the first step in a process of consuming air and fuel. The system requires the resistance of the air filter in order to get the proper vacuum to "SUCK" the fuel out of the float bowl and create the proper venturi effect.
Improper mounting and sealing of the airbox will create a small lean effect. This might seem like no big deal but you are inviting dust and debris in your engine that is doing slow damage by not having proper fitment. Fix it so you know it's not contributing to your issue. Pick the low-hanging fruit first.
Do not go and start adjusting anything at this point. It ran fine before. There is something wrong with the assembly or a component. Do not adjust your floats. Get it back to where it was. The moment you start tweaking everything is the moment you lose OEM settings which are a must-have for fine-tuning and maximum performance.
Fine-tuning your carburetor and multi carb syncing come at the very end following the proper procedure established by the Carburetor Gods.

I don't know if I can solve it but it sounds to me like you're not getting enough fuel. has it been sitting awhile or just start doing this randomly? If it's been sitting there's a pretty good chance you'll need to clean you carburetor. when gas sits in the bowl of your carburetor for too long it will get thick and smell almost like varnish. My Suzuki 250 4x4 had a similar misfire and cleaning the carb fixed mine.
