Hi, Anonymous 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.

Hi, Anonymous and the usual suspects are:
1. Retarded ignition timing.
2. Retarded cam timing.
3. Bent or burnt exhaust valve.
4. Massive air leak.
5. Intake manifold cracked or damaged.
6. Intake manifold seals have failed.
7. Wrong heat range spark plug.
8. Fuel delivery system running too lean.
9. Faulty Map, O2, MAF, TPS, sensors.
10. Faulty advance mechanism.
11. Faulty VOES switch.
12. Aftermarket exhaust headers tubing too thin.

Make sure that the cable is still working and hasn't broken from freezing up since it was parked. Had the clutch been causing any problems in the past? This clutch is not adjustable at the base where it mounts to the engine. Adjust the cable if needed from the handle. If this doesn't help, then it sounds like an internal problem. This would require taking off the right side of the motor. Just get a new gasket, and a clutch kit. The basket might be able to be saved with emory cloth. You can get a clutch kit at bikebandit.com

Hi mate sounds like you tested all the standard stuff you obviously know what your doing - In my experience when I get a bike like this where all seemingly is good and set correctly but no sign of life when trying to start 99% of the time ends up being the stator.
And I know it seems strange but I honestly up to about my tenth bike now where even though shows spark at plug when kicked over test, the stator still at fault when tested with Multi meter (way out of spec.)
If you have your repair manual flick through and get the spec ranges for the resistance on your stator then disconnect the stator lead at the CDI end and its very simple set your meter to ohms and plug into each pair of wires (usually 3 pairs) and see what readings you get
don't worry to much if you don't have the spec range as if it is the stator you will quickly notice you get zero reading on one pair of wires if not all three?
let me know if you want more clarification on testing
If all this fails to assist then my advice would a be leak down test to diagnose compression leaks, open valves, gasket leaks etc Then I would pay attention to the pilot circuit of the carbi, Double check your timing and valve clearances, Then I would be back to testing stator again?
Very rarely your coil pack (spark plug cap) can fail but be worth testing it when you have your multi meter out ( you looking for about 0.08 - 0.10 resistance reading on it) and even more rarely the CDI box can fail, no real way to test this apart from plug new one in and test if cures things...
Being that 5-6 years old and you know the bulk of how to fix and maintain this sound more and more like a stator problem..
On the up side if you do need to change the stator great opportunity to change cam chain aswell they run like brand new with full stator power and a brand new cam chain
cheers mate .... Good luck!

NGK brand spark plug BR8ECMVX is the stock plug for the bike. The proper gas / oil mix is 32 to 1. That means 4 ounces of 2 stroke oil per gallon of gas. The posting was not clear as to just what the problem is. If you are burning up plugs there may be a air leak in the intake system making the bike run lean. A lean fuel mix runs hot.

You are on the right track. Make sure your air/fuel mixture is good. How hard do you ride the bike? When was the last time you changed your clutch? A worn clutch can give you the same symptoms. Make sure your clutch is properly adjusted. If so, it probably needs to be replaced. The KIPs (kawasaki integrated powervalve system) should be cleaned routinely to avoid carbon build up.

hi there mate how are you the dry weight of this bike is approximately 97kg this is the dry weight which is without oil and fuel.. hope this helps thanks ladjr2

2005 kawasaki KX... | Answered on Aug 01, 2011


Everyone will tell you the oil they use is the best, so you are going to get a different answer from everyone that answers. I've been using BelRay MC1 for over 35 years and I have never had a lubrication related failure. I am still proudly racing 2-strokes at the top amatuer level. I have heard good stuff about Amsoil but I don't use their premix. I do use their suspension and brake fluids, though.

I suggest using BelRay MC1 at at least 32:1.

I hope this helped.

Remove the carburator to gain access. Unbolt the reed block from the back (rear) of the cylinder. You can replce the reed block assembly, or if you just got the reed pedals, they attatch with small screws. Use blue loc-tite #242 on the reed pedal screws so they don't loosen up. You will need to replace the gasket (s) with new ones and torque the cage bolts to spec. (Pay close attention when you remove it, so you know how it is re-assembled.)

check/clean the carburator, adjust the air screw... lack of fuel, causing the the engine to backfire when you close the throttle... adjust idle...

Change your oil immediately - replacing with the proper quantity and quality lubricant recommended by Kawasaki.

2005 kawasaki KX... | Answered on May 02, 2011


The clutch fluid may need filling up and replacing. If the lever and cabling are ok it could also be an issue with the mechanical parts. I am thinking on the tension of the clutch as it is engaged on the gear. You may have to inspect the inside as the cable is not transferring force to relieve the clutch. Check for linkages that may have come off.
