2008 ktm 250 sx.the bike starts and runs fine
Sounds like the main jet is clogged, or you have water in the bowl..
First try draining the bowl on the carb, drain into a glass so you can see if there is any water dirt etc... If there is water, it should be fine after that. If its the main jet you are going to have to remove the carb and clean it.
One other thing it may be. If it has a CV carb (constant velocity) the boot may be ripped on the slide causing it not to lift during acceleration.

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.

My 2006 Ktm 250 exc has been standing for 3 years, what should i check before starting it?Thank Mervin
Mervin, I'm not a motorcycle mechanic, but just knowing engines as I do, I would say drain the fuel tank and replace with new fuel and either a water remover additive or a more complete fuel treatment (Lucas makes some great products for that); pull the plug(s) and check them for any corrosion or buildup, replace if necessary; change the oil and filter; check the air cleaner; and check tensioning on any belts. I'd also suggest either replacing the battery straight away or just putting it on a charger for a while so you know it has a full charge when you go to start it - if you need to replace it, that will eventually become evident, but you should at least be able to get the engine started and see what else -if anything- needs doing.

Hi, i have a 250sx
The starter pinion attached to the kick pedal has an ratchet pin that engages in the engine shaft - the role of the pin is to allow the engine to turn freely once started. This pin is pressed on the shaft with a simple spring that in your case either broke or went out of position.
You will need to open that side of the transmission, access the starter mechanism and refit or replace the pin and its spring - it's a delicate job, work very carefully or you can do a lot of damage if you try to start the engine with the parts misplaced.

Oil drain plug case cracked 2007 KTM 450 SXF
Drain oil. Use degreaser to clean area. Use JB Weld & allow to set up properly before adding oil.

I HAVE A KTM 450 EXE 2004 MODEL AND I HAD TO REPLACE MY HEAD GASKET ANWATER PUMP SEALS AND NOW IVE GOT THE TINYEST DRIP OF COOLANT DRIPPING DOWN BEHIND THE FLY WHEEL WHAT COULD BE CAUSING THIS ?
It's a bad seal of the head gasket. You need a new head gasket and to scrape every particle of debris from the cylinder head and cylinder surfaces that mate with the head gasket. Use the factory specified gasket sealing compound and do a clean job - no blobs or pools of the stuff. The head gasket should lay flat on the surface of the top of the cylinder, and you have to make this surface free of grit, leftover sealant and any other foreign matter before you put the head in place and torque it down. Start with the head bolts just finger tight and then go by the manufacturer's specs for the pattern and amount of torque to be applied. Usually it is recommended that you get to the specified torque amount in stages, going around several times and repeating the torque pattern until you get that maximum rated amount. This will prevent the seal from shifting or warping and should make the gasket seal perfectly. This is the old school method of doing this job. and I have never seen this fail to produce good results. Take your time, be clean, and you will have the results you want.
