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.

Have a 2006 ktm 250 sxf seized rod to the crank got it changed reinstalled put motor back together now can not even kick it like somthing is stuck. Toke the clutch basket out, timing gear and water pump...

Your clutch basket is the link between the engine and transmission. Your kick starter rotates the clutch basket gear, which turns another gear at the engine crank. Remove either the basket or gear at the crank and see if the engine, and the transmission both turn. Sounds like the engine is stuck for some reason. At least you can cut the issue in half.

2011 250 sxf . owned for 8 months bought new.problem is the bike will die as soon as you give it gas.problem is very intermitent. may run great for a while then will start doing it again. been to dealer 6...

When you "give it gas" you are opening the throttle.
At that point the fuel system is supposed to supply the engine with more fuel to maintain the air/fuel mixture.
Check for anything that might be clogged like filters, hoses, fuel passages, etc.
If it is still under warranty you could void your warranty
if you work on it though in this case a warranty is meaningless if you have taken it in 6 times.
I've seen models where you could replace everything and
a week later it would refuse to run.
Sometimes it's better to leave the thing at the junk yard and buy a new one but that doesn't happen often.

Bike bogs and cuts out after about 10 minutes of hard riding

if the bike starts after a short time it could be a blocked filter or a carby problem needle and seat or a stuck float,if not the bike might be over heating and siezing partialy,hard to say without more info.hopes this helps

I have a ktm sxf 250 2006 model and when its hot it is very hard to kick start even with start assist spray and sometimes will not but it will roll start and also when you are at top of each gear mainly...

Using "Easy Start" or other ether based engine starting aerosols will damage the engines in the long run, reducing compression due to engine wear as the aerosol removes the oil traces off the engine bore and stripping the aluminiun from the pistons. If it were an old diesel engine, not a problem.
Check your petrol mixture settings and compression. As if the compression is low it will be hard to start.

2003 KTM 250 SX won't start. When you kick it, it starts to fire but never turns over. I accidently put the wrong gas in it. It takes 60:1 but I didn't put enough oil in it. It died while I was riding it....

If you have run the engine with too little oil then there is probably damage to the piston / rings & / or bore
Remove the exhaust to have a look

Ride Safe
