First drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

    sounds like it could be a plugged pilot jet, clean the carb extremely well, the pilot circuit is the smallest passage in your carb and usually takes nothing at all to get plugged. if you keep driving it by coast starting while the pilot jet is clogged it will cause the engine to run lean, will sound really nice and have lots of power until there is a nice hole in the top of your piston :) cant be too safe, rebuilds aren't cheap

Ok I have a 2004 kawasaki klx125 dirt bike. It was ran on mixed fuel. Will this mess or blow or cease the bike if continued to run on this


Hi, James it won't hurt anything, probably smoke a lot and may oil foul a spark plug, why not just drain it and replace with straight gas if your that concerned for more information about your question and valuable "FREE" downloads that you will need please click on the blue links below.

My kx125, can still start it and ride it without a lot of compression, it only gets compression about half way towards the bottom when kicking it, but it does start.. Any ideas??


Hi, Colin you may have a kicking gear engagement issue, do a compression test when the engine is at operating temperature should be around 125-130 psi. for more information about your question and valuable "FREE" downloads that you will need please visit the websites below.

How do I fix no compression on 2006 Kawasaki eliminator 125


No or low compression can only be from either valve failure in a 4 stroke engine, and/or serious internal engine failure. Cracked pistons, worn out rings etc. The engine will have to come apart and rebuilt

KMX 125 -99 i need to ask what part is controlling the thermostat/ignition. the thermostat is pending between normal temperature to very high temperature, when this happened the bike was happen to...


Hi, Alex the thermostat on your bike is controlled by coolant temperature when the bike is cold the thermostat is closed as the coolant heats up the thermostat begins to open if your coolant is overheating the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.
7. Engine idling too long or bike moving too slow.
8. Coolant too old needs to be replaced.

Replacing Kawasaki kx 80 kick start return spring


Hi, easy job, if your bike is waer cooled, you dont say how old it is the old bikes were air cooled, undo all the water pipes attached to the r/h case all the water will escape, you can leave the oil inside the gearbox, if you lay the bike on its left hand side, lift the engine and block it up to make sure gear lever is not resting on the ground, as this will disengage when you remove the clutch cover on the r/hand side, undo all the fixing screws from the cover remove kickstart lever, tap the cover gently to loosen the cover and remove when loose, if the case will not come off check further for screws, sometimes hide inside water pumps etc, once you are ready to remove the cover, keep the kickstart shaft pushed inermost so that it stays located within the engine, once ready fully observe the location of spring mountins within the engine and replace the spring

The bike will not shift into gear. The clutch has plenty of spring tension just will not engage


if the bike has been sitting for a while the clutch plates can stick together, you will still feel spring tension from the pressure plate. two ways to free it up.
with the engine stopped click it up into top gear, put the front wheel against a wall, pull in the clutch, and push on the kick start, or push start it in gear, pull in the clutch and vary the throttle .
Change the oil after the ride with good motorcycle engine oil.

Wont start by kick start but will by pull start


sounds like your idle jet is clogged, remove your carb and clean idle jet cause it won't idle or kick start without it...good luck to you friend...Tim
