Take the kill switch off and see if it starts. The killswitch may be permanently earthing the ignition.

SOURCE: new spark plugs last 10-15 minutes of riding

Hi and welcome to FixYa,

Offhand, the only factor to be checked that could foul a sparkplug for your bike would be the 2T oil injector/pump. There is too much 2T oil going to the combustion chamber. Either the injector would require restricting or for some reason, there is also 2T oil in the fuel tank (pre-mix).

Good luck and Thank you for using FixYa. Happy Holidays.

yes, you are correct, those are the two pieces that could solve your problem, but i would go first for your cdi, you may choose to have it tested first also, before you jump out to buy a new one.

SOURCE: problem starting ktm 2006 sxf 250

check inlet valve clearances. they close up making it hard to start exactly as you described. titanium valve coatings wear and ressesion happens quickly,a clean air filter must be maintained to prevent contaniments wearing valve coatings.

1996 KTM Duke quit running while riding

ok, your problem could be simple or could be quite involved. First thing to do would be to make sure its not a safety cut out i.e. kill switch on handle bar is set to off or is malfunctioning, side stand down while in gear, no neutral light. Also is the battery good?? A poor battery can cause the bike to have no spark as it can act as a resistor and not allow 12v to flow through the system thus preventing enough current for a spark. If its not that, hears where it can get tricky. It could be a number of other things i.e. If it has an immobilizer factory fitted or via an alarm system, Coil (which is usually not the case), Generator stator and pick ups or worse case a faulty CDI/ECU. You may want to get someone who knows about bikes to take a look. Good Luck

the flat battery shouldnt cause the problem and you said it has spark at the plug, so that sort of eliminates electrical problems.
if the carb is clean and it has good fuel, its a bit tricky to diagnose.
perhaps a sheared flywheel key,
blocked fuel line( it might have a tiny filter in the tank on the ends of the fuel tap pick up tubes)
or short in the kill switch may let it spark sometimes)

the ignition cant fail from sitting, perhaps the kill switch has corrroded, always put a spark plug in and ground it to the head when checking for spark , also check with a new spark plug

It wont start

well it could be because the bike sat for a while. with the 2 stroke gas being mixed with oil sometimes when it sits the oil sinks to the bottom and it will clog the valves fuel lines carb every thing. you should check.

07 KTM 85 SX LOSE OF SPARK

Did you do a compression check just for the sake of saying the motor did not seize? Have you checked by grounding the spark plug to make sure there is not spark? Your problem really sounds like a seizure. You may have lost the CDI box.

LOSE OF SPARK

Pull the plug back out of the cylinder and ground it against one of the head bolts, kick the engine over to see if you are getting a spark.
