SOURCE: bike only starts with choke on and wont idle

If your bike ran good previously - and nothing has been changed that would require rejetting or a needle adjustment, I would look for problems elsewhere. Such as:
Has the bike been stored for more than a few months at a time? If so, the carburetor jets could be plugged with fuel varnish. Only being able to start with the choke applied - and an inability to idle are both classic symptoms of this. Remove and disassemble the carburetor. Clean it and the jets out with carb cleaner and compressed air, then reassemble. Also make sure the fuel in the tank is fresh and that the fuel strainer (usually with the fuel petcock) is clean.
There are three ingredients required for combustion: fuel, compression, and a spark (at the right time). So long as you've got each of these - it has got to run.

SOURCE: 2008 ktm sxf 250 when engine is under load there

you may want to relube your water pump. this usually happens if the water pump cannot put out what it gets from the inlet valve. what will happen is that coolant will get stuck on the negative reservoir, then will get out of the over flow tube. you may think that you have too much coolant, but yet you only are running half.

avoid further damage and overheating have it replaced.

2011 KTM 250 SXF will not idle


Hi, Anonymous if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

Hi i have a ktm 450 sxf 09 and drown it in sandy water motor was still running when pulled it out but had filled up with sandy water i dumped the oil straight away and flush it out with new oit several...


Did you pull the carburetter off and clean it out also? If the bike was still running it has probably got a belly full of water. Great work on dumping and refilling the oil. But you need to check your carbs and your air filter. If the air filter is wet it will run for a little while then stop. Also check your spark plug and leads make sure they don't have water in them or haven't corroded.

So make sure you have good air, spark and fuel delivery.

Set on 08 ktm 450 sxf Cam timing


It could be a faulty coil inside the magneto, wrong timing or a problem ranging from cdi unit, wiring from the former up to the spark plug.Sometimes the cap that sits on the spark plug could cause this.Basically you are having a firing problem, which means combustion chamber is not getting the right spark for proper combustion.Sometimes even an improper ground from chassis to engine could be the cause of this problem.Hope this helps.Any questions then please ask..O I forgot, try a different spark plug,sometimes these could cause this problem.
