rewinding a stator is not difficult, find the right wire, better is square wire, as the heat conductance is better. If you select the same diameter you get automatically approximately the same amount of windings as the original. The sell the wire on Amazon and other places, Bing is your friend.

have u tried a new plug ? is power gettin to coil , put plug in cap and hold against a good earth point on head and crank over and see if plug sparks , if you dont see a spark try holding the plug and crank engine and if you dont feel voltage in your hand then remove cap off ht lead and repeat and if no voltage then check kill switch , if ok then check coil wires etc !

sounds like you bent a selecter fork in gearbox ! need to strip engine and check all parts inc cogs and bearings !

Sounds like idle jets are still clogged, they are really small and unless you check them, a standard cleaning of the carbs may not clear them. I use a nylon bristle pulled from a scrub brush to **** out the pilot jets.

i think you got gearbox problems

Starter relay

increase the fuel intake it should be a little screw

have you got a spark and is fuel getting to the spark plug ? check these and you might have your answer ! P...

Sounds like your clutch is out of adjustment, or needs to be bled. Most of the ktm's use a Magura hydraulic clutch which can be bled using Mineral Oil. DO NOT USE BRAKE FLUID.

CLEAN CARB AND REPLACE FUEL FILTERS CHOKE ENGINE TAKE OFF AIR FILTER REMOVE SPARK PLUG AND RUN IT IDLE 5 MIN PLACE ALL COMPONITES ON IT AND DRIVE

I bet you got water in your gas through the carb or in the spark plug check the oil for what looks like a raindow .

Do you have the owners manual with you? If yes, then you can check your manual and look for the page where you can check the location of the oil.- IRC Motorcycle Tires combined with good quality components

The F1 light is an engine management error, take it to your nearest dealer and get them to run their diagnosis machine on it. You may have a mixture problem or an ignition timing problem.
