could be a blockage in your cooling system or your bike is overheating. i would start by flushing the radiator and refill it with a mix of coolant and distilled water.

SOURCE: I CANT SEEM TO START MY BIKE 250 KTM 2 STROKE

check to see if it is firingif it`s not firing it`s probably the coiland if it`s firing check to see if it`s easier to crank over than usual if so then there is no compression in which case u may have a big problem but i doubt that`s the problem 9 times out of ten when a bike wont start it`s the fire or maybe u forgot to turn the gas off and it`s flooded if u want to know if it`s flooded take out the spark pluge put a lighter by the hole and crank it over and u might be able to dry it out like that too

Yes. If you look around, you might be able to get a kit to eliminate the oil injection pump.

Check the pulse generator next to the flywheel - it's known to fade when hot.

Hi ave got a ktm 125sx 02 its just had a bottom and top end rebuild bike starts and runs great but there is still a rattle from the engine could anybody help thanks


Lots of engines make characteristic noises and air-cooled 2-strokes have lots of characteristic noises even when new and even when there is nothing wrong.

If you have just spent a parcel of money on it your first port of call should be to the person or dealer who carried out the work. Having a top and bottom overhaul means a world of different things to different people. If you don't know what has been done and what needed to be done you will be somewhat in the dark and at a disadvantage with perhaps unrealistic expectations.

Perhaps the engine hasn't had as much of an overhaul as you thought. A full bottom end overhaul is a good deal of cash and lots of work that would make it as good as a new engine again. Maybe the dealer decided for reasons of economy to refit some of the old parts instead of replacing everything.
I suggest you read your invoice and then go and ask some leading questions.

My 2003 sx125 just stopped running, I have fuel. pulled the plug and I do not see any spark??


Replace the spark plug first. Cheapest/easiest thing to try and most popular failure on a two-stroke. If you still don't have spark from the coil wire, then you have to troubleshoot the coil and stator. Also make sure that your kill switch is not shorted or grounded out either at the switch or along the wires.

Ktm wont start


sounds like you may have over adjusted the decompressor, back it off to where it was, this would make it backfire.
To kick them, push the kickstart through its stroke until you get to feel the compression as it approaches the compression stroke, then use the decomp to kick it just past top dead, let the decomp go and then kick it, no throttle
