What is wrong here ?


my thoughts are its sucking in trans oil from a bad main seal on the primary side.Other possibilties are you over oiled your airfilter or you are putting in to much oil in your mix .

What is the fuel mixture for a 2002 KTM 300 EXC 2 stroke? Thanks


WIth Shell v-power and your favourite 2-stroke oil, you could go 50:1 (that's from my dealer). I have been running 50:1 since my 2002 300 EXC has been new, always use new mix for every ride, and drain whatever leftover is in the tank every two weeks.

I have a 91 ktm 300 exc and it bogs down and dies when i isnt choked and at a low rpm


Your carb needs to be cleaned. More specifically, the pilot jet, but if it's clogged it'd be best to go ahead and clean the whole thing.

Remove the carb from your bike and then remove the bowl from the bottom. You'll then be looking at the jets and float valve. The jet causing your issue is the smallest one. Remove it and carefully spray it out with carb cleaner. Then hold the jet up and see if you can see light through the hole and that it appears clean and round-meaning no obstruction left. Locate the mixture screw on the outside of the carb. It should use a flat screwdriver. First turn the screw in and count the number of turns. Then remove the screw, followed by the spring and ,if applicable, a small o-ring. Spray through the hole and make sure it goes through and comes out somewhere. Replace the screw in the reverse order and set to the original setting you counted in the beginning.(rough estimate is 1.5 turns out. Cleanliness is the key to the carb working. So keep it spotless inside and reinstall. This should take care of your problem.

KTM 520EXC Starts with choke but you cannot take off choke


well you hit it right on the head there,, its the jets in the carb blocked up,,strip down carb and clean out all the jets with carb cleaner and compressed air dont go poking any thing into the jets as you will distroy them that way,,, another way of clearing the jets out that you could try first is,,,take off the air filter and start the engine up on choke in needs be,,rev the motor up high and slam your hand over the carb intake,,removing it just before the motor cuts out do this a good fuw times and it some times??? only some times clears the carb jets out for you

Runs great with choke on but continues to die when choke is turned off. 2008 ktm 530 exc


Hey mate,

you definately have a problem with your fuel system, I would say you have had some dirty fuel thru your bike, the first thing i would check would be the fuel filter between your tank and the carby then if still does not run drain your carby bowl... after this if it still does not run you will need your fuel system/carb stripped down and flushed would recommend getting this done by a mechanic as there is alot of small parts involved...

Hope this helps

Smoke


If it's liquid cooled then that grey smoke is more than likely steam ( the head gasket is on it's way out). If it was burning oil you would able to smell it.,,
