Remove the slide from the throat of the carb. Move the clip on the jet needle one notch lower. Two notches may be needed but start with one.

A “very helpful” rating for this answer? Thanks!

2003 kawasaki KX 125 powerband sputtering


Hi, Nick 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.
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.

Head gasket or intake manifold gaste again 96 k1500 5.7 vortec. starts runs idles and drives rough it likes to **** while trying to drive almost as if it wants to stall out. i put my scanner on it and


The website has software that looks for obscene words.
I would think a compression test would show if the cylinder is having mechanical problems. And yes the intake or head gasket could be leaking again, especially if the intake or head were warped or cracked.
Have you checked fuel pressure ?
Does the spark plug for cylinder 5 show signs of coolant leaking into the cylinder ?

Kdx 125 sputters just before the "powerband" kicks in


I used to ride enduro in the 1980s on a KLX 250 :>)

Sounds like you have two issues.

Your spluttering and jolting sounds like a defective Reed Valve, but could also be carburetor float level problems. If it is runs fine when on the power band, then the carb is fine. For the cost, I would replace the reed valve.

http://www.athenaparts.com/eng/sections/view/128/carbon-fiber-reeds-for-intake-reed-valve/page:6

Regarding the electrics, this could be a few things. Check all the earthing points, especially the one on the negative side of the battery. Take the wire off where it grounds to the frame, clean and apply Vaseline which stops corrosion and is electrically conductive. Check all the connectors that you can find. Pull them and make sure they are clean and sealed. Vaseline is good on these too. The specs below confirms it is rectified and regulated. Check the output voltage of the alternator with a test meter. Check the battery is as spec Battery 12v 3Ah and get it stress tested, or just replace it, if it older than 3 or 4 years.

You really need a good workshop manual. I had them for all my scooters and bikes.

I recently put a new head gasket on my '99 KX 2 stroke. It blew the head gasket and drained all the radiator into the lower end. It was a pain to clean out, but I reassembled everything, took the bowl...


Hi, Brandon nice novella, it could be a funky power valve and they are moderatley easy to clean/repair and you will need the free manual provided below as for a gasket/o-ring you may be able to reuse the old one if you are careful removing it, worse case scenario you can always make a gasket out a cereal box and use high temp silicone for more information about your question and valuable "FREE" downloads that you will need please click on the blue links below.

Normally water gets in through the head gasket, sometimes you can hear if the head gasket has blown. One way of finding out is to take it to your dealer and ask them to do a compression check that will tell you if you have a duff gasket. You will also notice a slight drop in performance.

If your intake gaskets are leaking, when you dump soapy water on the gasket, it should bubble like crazy ( when it's running). If you can, run it with the rad cap off and watch for bubbles. If it keeps bubbling, you probably have a head gasket problem.

Problem with the powerband on my kx250


sounds like you need a new power valve in the cylinder. They can go bad and thats how they will act. You have to take the cylinder off to change it. If your that far you might as well put a new piston and ring in it.
