Question about 2002 Honda XR 250 R
My 2002 XR250 idles and runs fine in lower RPMs (idling in nuetral, going slow in 1st and 2nd gear), but bogs badly and stalls as soon as I gas it. I'm sure it's a basic carb problem but I'm not sure what to check first.
The main jet need cleaning.(you should clean them all though)
Main Jet: Main jet comes into play at three-quarters open to full throttle conditions. CRITICAL to high-speed engine operation. Not only does it meter the gas into the engine, it can aid in cooling the engine as well.

Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving
