Are the exhaust fumes thick? if so your flooding out but chances are the accelerator pump can't keep up with fuel.,

2014 KTM 250 SX plug fouling


air filter dirty can cause it to run rich. Should be cleaned every 10 hours of riding.
Mix should be at 40:1 in winter and 36:1 in summer. Use a ratio right dont guess on the mix.

Finally - get a JD jetting kit and install it! Crucial for all ktm bikes.

Curious what jetting are you currently running>

Hope you have kept notes on all the carb setting changes.
Did the problem start when the exhaust was modified? If not it may not be a carb problem.
Does the problem change if the engine is cold or hot?
Does it make any difference with the choke on?
Is the air filter new and clean, new plug, valve clearances adjusted, new oil.
I know I havent answered the question, but hopfully gives you a few more things to check

Have a 2005 ktm 525 exc,after 20 mins of riding it starts missing and stalls when slowing down for gate or log ect,when i try to start it takes a bit and will pop or backfire through exhaust, had jd kit...


sounds rich, especially if its a problem when it warms up, was the JD kit a much bigger main jet,might need to try standard main, is it standard exhaust, I assume the air cleaner is clean and good condition, the foam can deteriate over time.Not sure if you have a hot start button or lever, this leans the mixture, if you have one and it helps then its definately rich

as a non related hint I use moreys upper cylnder lube in my WR it starts easier, idles easier, doesnt stall as easy under hard braking, and doesnt seem to get as hot and ping when working hard in tight bush.

When i accelerate flat out in 1st gear there is a flat spot,what can it be 2001 ktm 400.


A couple things you can check. One is make sure the carb float level is high enough.It should be set exactly at the factory spec.Another thing is make sure the carb main jet is not restricted, a piece of sand or something. Make sure the air filter is cleaned and in good shape.And a fresh spark plug is a good idea.You can also call the KTM dealer and see if they can help. They might have a recall type problem they could tell you about. I hope this helps you and your bike.

Ktm 525 missfires after it gets warm


First take a look at the plug color. Should be tan to a light chocolate. White is too lean. And don't overlook the valves. Adjust as needed.

A LOT!

KTM does not provide a spec for this. If you think you are low on compression, you will need to perform a leak down test on the motor to determine if work is needed.

Starting after servicing


dirty air filter? anything clogging the inside of the air boot?and since u drained AND bled the radiator fluid, did u fill it back up to the top with specific dirt bike radiator fluid?pilot and or needle and main jets clogged and clean your carb. if your pilot jet is clogged you;d be kickin the bike all day. these small things will prevent your bike from starting so check them
