The problem you are having is most likely due to tight valves. Your exhaust should never get "red" unless you are running a turbo on the bike, in which case that is completely normal.
I would first check the exhaust system for blockages, these usually happen around couplers or in the diffuser in the rear of the exhaust. This is much like a catalytic converter going bad. Put your hand at the rear and make sure you are feeling good pressure coming out of the exhaust. I'd recommend you do this when the engine is not hot so you don't burn your hand. If you feel good pressure coming from the exhaust then you most certainly have tight exhaust valves and this need to be addressed very soon or you will cause serious damage to the engine.
Best of luck!

Exhaust glows red hot on dr650 after running on idle for about a minute, spark plugs very black/covered in carbon build up. Shouldnt the exhaust only get that hot running lean? surely then plugs would


If the bike is equipped with any kind of catalytic converter, then the extra raw fuel is burning up in the cat causing the glowing hot exhaust, and all that unburnt fuel in the combustion chamber is fouling the plugs.

I just got a 1997 zx9 and I just changed out the head gasket,but now my bike is over heating the head exhaust pipe is getting red, so I was thinking it was the timing so I looked at it and it looked good,...


I think you are way over your head here ... evidenced the red hot pipes. Could be time ... could be you didn't do the head gasket properly. Might be time for a professional to check out your ride.

Back jug exhust turns cherry red idialing


If you allow the engine to idle long enough, most any pipe will turn red. However, this is usually the result of a lean mixture if it does this in a very short time. The exhaust temperature of a gasoline engine is somewhere around 1200° F and the steel pipe will glow red at this temp. It depends on air flow to keep the temperature below this. If it gets this hot too quickly, you may have an intake leak on that cylinder at the manifold junction. I'd try putting new intake manifold gaskets on first. Since you didn't tell me what year, model, and what type of fuel system you have, I can't advise you any further. If the gaskets don't remedy your problem, take it to a performance oriented shop that has a dynometer and an exhaust gas analyzer and have them check your bike.

Good Luck

Exhaust manifold becomes red hot when revving up engine


Hi there, yes this is normal. Not the best thing to be doing to the bike. It will heat up fast when there is no airflow over the manifold or motor. You must be holding it at revs for an extended period for this to happen. Can I ask you why you are doing that...It is a trick to show off perhaps.....but thats all. If you need to do this sort of thing, to resolve a problem or other, it is always a good idea to have a fan moving air past the engine to cool it, or it will heat up fast, and eventually overheat. The motor is designed to be moving for cooling when throttle is on, not stationary.

HI, I AM LOOKING TO REPLACE THE ENGINE BOLTS ON THE FRONT OF MY BMW R 1150GS BUT AM FINDING THEM HARD TO REMOVE, I'VE BEEN TOLD THAT HEATING THEM WOULD HELP BUT AM A BIT WEARY OR DOING THIS. CAN ANYONE...


If you want to heat the bolts safely you can use a kettle of boiling water or two kettles of boiling water...
Once they are hot get the wrench on the bolts and pull with all your might!

The exhaust on my ttr225 gets glowing red hot ,what do i do to fix this problem?


Start with richer main jet in the carb. Next, replace any rubber manifold parts and seals between the carb and the cylinder head. Old rubber does not seal well and can let outside air into the fuel mix. This leans the mix which means it runs hotter than it should. Also be certain that the exhaust is clear of obstructions and that the interior of the muffler has not collapsed. Be sure you have the stock spark plug for your bike. Plugs have heat ranges and too hot a plug can be a problem. Wash the cylinder cooling fins if they have any mud/dirt build up. Please rate my answer.

Glowing exhaust header yamaha wr250f


It won't be valve timing or clearance. The fuel/air mix would be the culprit. Clean the carburetor with special attention to the idle circuit. Remount the carb with new manifold gaskets. A manifold air leak will mess up the mixture. Also, get a new spark plug one heat range colder than stock. Hope this helps out!

Please rate this solution. Thanks!

Charging system failed. replaced completely, failed again


Hi and welcome to FixYa,

Initially, pls re-check your voltage regulator. Common/usual signs would be discoloration of the connector, burned/corroded spade lugs of connector, partial melting of the epoxy/plastic packing, the 3 same colored wires (usually yellow) looks bloated/heated up.

Good luck and Thank you for using FixYa.
