SOURCE: 91 kx 250 blows smoke and drips alot of unburnt oil out the pipe

Does it have a stock pipe,carb,any modifications! If its stock,I would put a new ring and piston in it,it seems like your getting a lot of blowby,also make sure your air filter is clean. It would help if you used an iridium spark plug.

SOURCE: why does my kx250f pipe get red hot to where it

Several things are possible. The baffles inside the muffler may have partially collasped causing a restriction in the exhaust. The fuel / air mixture may be too lean. A lean mix burns hot. The stock main jet is a #178 (stamped on the jet). Try a richer jet, #180 or #182. Also, use only premium gas without ethanol. Be sure your gearbox oil is clean 10 w 40 motor oil. NO SYNTHETIC LUBRICANTS. Check the radiator coolant flow and temperature to be certain the engine is getting cooled as it runs. Be sure mud /trash is not blocking the radiator fins. Also check the spark plug. The stock plug is an NGK CR8EB. Replace it with a colder plug, NGK CR9EB

SOURCE: 2002 ninja 250 idels good

The power band on a 2002 Ninja 250 does not kick in till you hit about 5000 RPM. The newer 2008 and up 250's kick in about 3000 RPM. There is a website devoted to the Ninja 250 that might give your more background into the motorcycle: ninjette.org You may want to replace your spark plug caps they may be robbing of the spark you need at take off. They simply unscrew off of the end of the wires. They should read 5000 OHM's no higher , no lower. If you purchase new NGK brand plug caps they will only cost about $5 each.

SOURCE: Why does only 1 exhaust pipe on my ninja 250 get

Try unplugging one spark plug at a time and see if the engine will run on just left and just right cylinder. The cylinder thatwont run may have a clogged carburator or the valves may be too tight causing a low/no compression on that cyliner. Also a vacuum leak at an intake boot would cause a lean condition and a hot cylinder. Be certain you have spark at both ( properly gapped) spark plugs before **** these tests.

sound like you need to have the catalytic converter checked. when a catalytic converter gets plugged up it will cause the exhaust pipe to get really hot or red. and show the symptoms you are describing. a good muffler shop should be able to test it. good luck

Rear jug getn hot 2 min after start up exhaust getn red hot...stage 2 jet kit..vance&hines exhaust .no baffles 43000 miles


glowing exhausts indicate valve timing, ignition timing or lean fuel mixtures
AS you have altered the jets I would be looking at air/fuel mixture for the rear pot
It is probably the same for the front pot but with an air flow on the exhaust pipe you will not see it getting red

Exhaust pipe turns red hot Yamaha yzf


Hi, Anonymous a YZ is a motocross bike designed to run flat out that being said if you are strolling down some scenic trail at a slow pace or letting the bike idle for a few minutes your header pipe will turn cherry red, why you ask? It is not a street bike, it is designed for competition and weight is a major factor all necessary components are of the smallest and lightest design necessary to maintain performance under extreme conditions ie. small radiator and inside frame oil reservoir that doesn't get cooled, the majority of your riding needs to be at high speed.

2006 Kawasaki KX 250 pops at high RPM?


Hi, Bill if your carburetor or exhaust is:
COUGHING is usually caused by an air leak in the intake system and will generally have the same telltale signs, a wet or damp build up of oil/gas seepage at the intake manifold to cylinder head or carburetor to intake manifold connection and in rare instances a worn throttle plate shaft and or seals.
POPPING on deceleration is usually caused by a lean fuel condition or an air leak in the exhaust system and is generally located where black carbon soot is seen as a flashing build up from any joint connection. This condition can easily be remedied by removing and cleaning both joint pieces and reassembling with high temp silicone and torquing the exhaust clamp to the proper spec.
SPITTING is usually caused by a faulty accelerator pump and or nozzle, or the float bowl needle and seat leaking and overflowing through the main jet mixing well nozzle, or the air-fuel mixture screw is adjusted too lean.
BACKFIRING is usually caused by a sticky/tight intake valve or a timing issue, 180 degrees out or cam chain off 1or 2 teeth.
