Hi guys! I am new here, I am from Romania.
I recently bought a used Kx250f 2011(injected) and making a long story short i did not tested the bike because it was a rainy day, only started the bike and let it idle and rev a couple of times (i had no experience with bikes). When i took the bike for a ride, after 2km the bike would not keep an idle, it stalled and died if not keeping it accelerated from the throttle.
In short i ended up rebuilding the head with new titanium valves and seat cut at specialised service. This did not solved the issue, the bike still will not idle.
After watching some videos on youtube i have seen a guy having the same problem because of the ignition coil. New ignition coil added and the problem is somewhat better, it wont keep an idle when cold but when hot is idling, only if the idle screw is at the max left (max rpm)
I did self diagnose and found a faulty connection to throttle sensor. Fixed with a new connector, no more error codes. This did not fix the problem.
Cleaned and checked the injectors with carb cleaner, injector jets look good. This did not solve the problem.
I took it for a ride after all this and it is not working right, it is stalling and when i press the clutch the engine revs very hight at idle (might be because the srew is at max or a stuck injector).
Also it is leaking oil from the breather hose after a ride, only after you ride it.
The timing is good, checked, the valve clearance is good, checked.
Please guys, help me, i am out of ideas and out of money.
