20 Most Recent 2011 kawasaki KLX 250 Questions & Answers


Hi, Dan_wassmer 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. A 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

if it is a water cooled engine the ring gap at the bottom of the cylinder should be around .010"
rings have to be installed the correct way up or the compression doesn't help push the rings against the cylinder walls for effective seal
piston skirts will touch the cylinder walls as the pressure pushes the piston to one side as it pushes the piston back down the cylinder
I have to ask did you put an old piston back in the new cylinder
was the new cylinder standard size or over size
what was the ring gap before you fitted them to the piston
did you use new rings or the old ones --maximum rin gap is .025"
rings don't wear in , just wear out
why did you replace the cylinder in the first place
was it because of low compression or taper wear
as silly as all this seams it is all very relevant to your question

Buy a manual from a company such as "Haynes" or "Clymer" these will give you all of the diagrams you require for all systems amd models.

Hi, Darryn my guess is probably, parts swapping is common with most motorcycles when it comes to interchangeable or compatible parts from one model with another "EXCEPT" for the CDI's they are year-make-model "SPECIFIC" the best thing to do is call your local Dealership Parts Department or a reputable independent shop. If your location is not near a shop then go online and find a parts catalog or "FICHE" and match part numbers depending on your criteria.

Hi, Swwallis 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.

remove choke cable and lubricate with machine oil

kawasaki KLX 250... | Answered on Mar 14, 2014


By "flicking" sounds, do you mean a series of rapid "clicks"?

Usually a series of rapid clicks when trying to start is an indication of low battery voltage, or a bad electrical connection, usually a ground.

Get an automotive jumper cable (use only ONE of the leads, let's say the BLACK one), hook one end to the battery NEGATIVE terminal, and the other end to a bolt head that mounts the starter motor to the engine case, and see if that helps.

If so, it is a ground issue.

An old time Harley trick is to attach a SECOND ground cable to the battery negative terminal, and the other end, remove one starter mounting bolt, slip the bolt through the cable "eye", and reinstall the bolt.

The problem in this case is that most bike engines are made out of aluminum.

While aluminum WILL conduct electrical current, it's NOT the best conductor in the world.
This is why copper jumper cables are much better than aluminum ones, and why they found out (the hard way) that aluminum wiring in a house is no good!

NOW, if when you try to start and you get a SINGLE click, this usually means either a bad starter relay, or bad starter solenoid.

We used to buy premix from the dealer, although now I just use a 50/50 mix of Halfords 500ML coolant and water.
