matan9884,
I'll strongly suggest that the pilot jet and related passageways inside the carburetor need to be back-flushed. Cleaned with an aerosol carb cleaner and compressed air!

Wash the mud and dirt off of the entire bike prior to any disassembly, if at All Possible!
Otherwise you may make a bad situation Even Worse!

I agree. You should open the carburetor and remove the two copper jets and make sure they are clean. Then spray carburetor cleaner through all the Little openings.

If you need help in Cusco: Yamaha, Honda and KTM dealers are all on Calle Wayna Capac.

FIRST THING: Drain float bowl; contaminated fuel can cause/exacerbate symptoms observed. SECOND THING: Be sure fuel in tank is wholesome.

The pilot jet may be clogged, but . . . the pilot jet only dominates idle fuel mixture. (The pilot jet has a little bitty TINY hole, compared to the main jet. Don't see how even a clean pilot jet could process fuel beyond 1/4 throttle; certainly not at the rpm where the OP is having problems.) Since wider-open throttle problems exist, other jets and galleries may be clogged also.

A good cleaning, as indicated in Tom Schmitz' excellent "Carb Overhaul" videos: http://www.klrforum.com/how-tos-tech...-overhaul.html (place cursor on blue text and left-click) should set things aright.

Another possibility, occluded fuel flow. Gasoline should flow freely into the carb from the fuel tank when the engine is cranked. If not, vacuum-activated petcock and fuel lines should be checked out.

FINALLY: The fact the engine runs only with the "choke" on suggests the possibility of a diaphragm air leak. Unless the diaphragm is whole and sealed air-tight, the slide and needle will not lift adequately, will not provide sufficient fuel from main jet, resulting in a fuel-lean condition. A fuel-rich mixture from the "choke" (starting enricher) will permit the engine to run with a diaphragm air leak.
