Question about 2005 kawasaki KLX 110

1 Answer

KLX 110 not getting enough spark i think to burn the fuel

It is an all stock KLX 110 and was running perfect, the kids fell over a few times with it nothing major and still ran fine. the problem now is that while riding it on a straight trail it just died. we put a new plug in it cleaned the carb out like new and tried messing with the air screw, we also cleaned the air filter, now with the air filter off it seems to run a little better but never had this problem befor. the bike was new and only been ridden 4 or 5 times. I had a mechanic test the coil with the bike off and it was reading 7.4, they told me it sounded mor like an electrical problem. I just cannot seem to narrow this down. Any help PLEASE.

Hi, Jason and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a "LOAD" test if necessary, your battery may show 12.5 volts but have little or zero amps and needs to be replaced.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, points/condenser ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Air/fuel mixture screw improperly adjusted.
10. Accelerator pump damaged or not working.
11. Water or dirt in the fuel system, carburetor or filter.
12. Restricted, blocked or kinked fuel line.
13. Fuel tank empty.
14. Fuel tank contaminated with ethanol sludge.
15. The gas cap is not venting properly or fuel tank venting system blocked.
16. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
17. Needle and seat stuck closed in the float bowl.

SOURCE: klx 110 2006 stalls when choke is pushed in

i'd say the carb is gummed up especially the pilot jet (#16158) in this pic of the USA carb. may have to remove the carb & bowl and then remove the pilot jet (w/ flat head screw driver) and clean out the tiny holes.


the carb slide is installed backwards (turned 180 degrees). its #16025 in the pic. i've done this before on my daughter's XR70 and Z50. you'll know if its this when you move the choke lever, RPMs increase and decrease.

hope this worked for you and was fast enough.

Hi and welcome to FixYa,

A couple of initial checks (after battery has been fully charged):

  • presence or absence of spark when starting - unplug 1 of the sparkplug wires. Attach a spare known good sparkplug and lay it against any metal part. Crank/start the engine. Chaeck for sparks;
  • try starting with the clutch lever pulled in and/or the sidestand folded up;
  • exercise the 'Kill Switch' and the ignition switch;
  • loosen the drain screws of the carbs.  Note the quality and quantity of fuel that would flow out from the drain hose. Compare between all carbs.
Please postback results of above initial tests.

Good luck and thank you for asking FixYa.

SOURCE: my 110 startied dieing and acted like it isn't either getting gas

you could be getting to much gas or it is to lean or to rich.when you took off the carb did you mess with the fuel adjustment screw?if you did than you need to set it according to the factory specs

SOURCE: My 2007 Kawasaki KFX50 starts and idles fine, but

Unrelated Recall Alert: CLICK ME

Some articles I have read suggest removing the stock auto-choke carb and replacing it with a Honda CT70 Carb. Check with a local shop to verify, I do not own either and am just passing along the info.

Another solution suggested by 'OneRide': Try it with the gas cap off. The tank vent might be plugged. Possibly plugged fuel filter. Are you using the choke correctly?

This seems to be a very common problem and no 'one' solution to fix it.

I hope this helps.

Can you put two stroke gas in this four stroke klx 110

You can put the 2 stroke gas in if there's nothing else available and you're in a pinch but it will eventually foul the plug and create carbon in the combustion chamber if you do it regularly.

Klx 110 backfires and cackles when i let off the gas. also dies when i run thru a water puddle

Check your ignition wire/boot for leakage; it sounds like that's your problem. An easy way to do this is run the engine at night with no lights on; if you see a miniature lightning show, you know there is leakage.

My bike was runnin perfect an it cut out when i was riding it now it wont start it sounds like it wants 2 could it b the spark cplug

Lots of things can happen ( run out of fuel) overheat and ruin the engine. Yes the spark plug and the related ingtion. key on battery power, kill switch. wiring to the handlebar switches. Remove the plug and lay it on the heasd where you can see the tip with the wire connected and crank the engine and see if it sparks good ( it'll be bright and you can hear it too) if it does and theirs little or no deposit on the plug (you said it was running prefectly) Then move on to fuel, check to see if theres enough and that the valve is turned on. next if not found remove the fuel line for the carb. being careful as gas should come out but it might not as the filter in the valve on the tank may be stopped up or the vacume line connected to the intake side of the carb may have come off or off the fuel valve. Some fuel valves have a ( prime ) position and the fuel will come out anyway in this position and with it comnnect to the carb if it still doesn't run the problem can be in the carb. Before going into the carb you might check compression first. With the plug out put your finger or an compression gauge in the plug hole. The measured commpression should be over 100 PSI or blow your finger right off the hole. If this is in order then remove the air filter connection to the carb and squirt a little gas in the carb ( just a little) and crank it with the key on, it should start and die or even keep running, if it does put the air cleaner hose back on and if it contrinues to run, take it out and have fun.

What kind of spark plug does a klx 110 have?

Where is the spark plug located on a klx 110?

It is almost underneath the plastic where the fuel tank meets the seat. You will see it at the top of the engine block with an HT lead on the back of it. You might need to take one plastic off to get to it.

Change the HT lead too if you have the cash. Best to match the ignition parts with the same age parts.

Hope this helps and vote for me please: )

Klx 110 started smoking grey smoke burning oil there is also oil on the end of the exhaust pipe. bike still runs good.

If the level of engine oil keeps going down (even in very small amount), then it shows a problem with piston rings. Hope it helps and let me know if you need more advice. Please don't forget to rate the answer it helps me, thanks!
