SOURCE: Exhaust glows bright red.

These bikes dont like to idle for very long. If you ride at a reasonable pace, it shouldn't glow for long. If it persists... Your jetting is too lean. Check out for a pictorial step by step how to re-jet

SOURCE: the exhaust pipe gets red hot after only a few

Usually this indicates a lean fuel/ait mixture. Remove the main jet and note the number stamped on it. Go to your dealer and give him the VIN from the frame. From that number he can tell you exactly what year, model and engine size you have. Now ask them to check the stock main jet number. If different than what is in the bike then get the stock jet. Check the manifold between the carb and cylinder. If any rubber seals or hoses are hard, then replace them. This will eliminate air leaks on the intake leaning the mix. The image below is for a 1995 model. On the carb main jet and nozzle (in red), make sure they are very clean inside and out.

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

2015 Moto Guzzi v 7 special is rough idling and exhaust pipe is heating up to red hot?

Could be running way to lean and the fuel may have too much alcohol or water or the injectors may be clogged/restricted.

I have 1998 ford expedtion runs rough pipes get red hot. took pipes loose. no power still. put new plugs no luck please help!

It takes a lot of heat to make the exhaust pipes get hot enough to glow red. It is a dangerous condition and can lead to a vehicle fire. A clogged catalytic converter or manifold could cause this, but ultimately the heat from the exhaust fumes is not exiting the system properly. Even a clogged tail pipe could cause this. A vandal might have stuck something in the end of the tail pipe.
It is running rough because it cannot push the exhaust out and therefore cannot take in enough air.
Regardless of the cause, have this inspected and the blockage/clog removed repaired and do not continue to drive the vehicle with this condition.

2007 Honda 919 exhaust pipes red hot

Hi, Sandy and the usual suspects are:
1. Retarded ignition timing.
2. Retarded cam timing.
3. Bent or burnt exhaust valve.
4. Massive air leak.
5. Intake manifold cracked or damaged.
6. Intake manifold seals have failed.
7. Wrong heat range spark plug.
8. Fuel delivery system running too lean.
9. Faulty Map, O2, MAF, TPS, sensors.
10. Faulty advance mechanism.
11. Faulty VOES switch.
12. Aftermarket exhaust headers tubing too thin.

Catalytic converter stopped up. Pipes got red hot. Replaced Cat. Conv. car runs good, then started random misfires, pipes got red hot again. What is exhaust part that is downstream of Cat. Conv. could it...

If the exhaust system was plugged the engine wont run, normally. It will start and idle until the back pressure is such that it can't take in more air/fuel mixture and then stall.

After the converter, there may be a resonator, and then the muffler. Is any exhaust flowing out of the tail pipe? You might try hooking up a scanner and see what your oxygen sensor(s) is/are doing.
Also, scan the MAF(mass air flow) sensor assembly.
Sound like the engine can't breathe, and its getting to much fuel.

Exhaust red hot,why?

It is quite normal for the pipe/muffler connected to the engine exhaust port to get very hot, especially when the engine is working hard running at speed under load. During daylight it is usually not noticeable, but at night it will visibly glow up to a bright red.

What tempature should my rmz 450 run at? Also why does my header pipe get red hot after running for only five min. at idle?

The cooling system on the RM-Z450 was designed for motocross and only works efficiently with air flowing through the radiator. You should not sit at idle for more than a minute or two if at all possible. The extreme high output of this engine causes extremely high exhaust output temperature. The pipe temps can reach 600-800 degrees F plus all the way back to the silencer. This is normal on all modern racing 4-strokes. There are a lot of aftermarket products available that help increase the cooling system efficiency. There are also several products that help insulate critical areas from engine and exhaust heat including shields for fuel tanks/lines, the carb/throttle body, rear shock, and plastic body work.
