What makes your cherry red exhaust?
The exhaust manifold does get very hot but if it is glowing cherry red it could be a restriction in the exhaust/ restricted catalytic converter, it could be a lean air fuel mixture, or retarded ignition timing all of the above should cause a loss of power or fuel economy.
What does it mean when your ATV exhaust is red?
Picture this: You just got back home from an intense ATV trail-run when you notice that the exhaust is glowing red hot. You naturally start worrying whether this is normal or not. A glowing red color is usually an indicator of fire-bursting temperatures, which is rarely a good sign, especially when it involves our expensive toys!
Why does my bike exhaust turn red when idle?
Even if the bike produce more heat when riding, you may even find that the glowing gets worse when standing still at idle. This shows how important the airflow is to keep the system cool. So if your exhaust is glowing red when standing still at idle, it may just be because of too little cooling.
What causes the exhaust on an ATV to run hot?
An even more accurate way is to perform a so-called leak-down test. Exhaust leaking before it exits the system will result in a lower back pressure, which may cause the bike to run hot. Look for loose clamps]
Why are the pilot Jets on my ATV turning red?
Soaking them in a cleanser is often not enough to get a good result cleaning the tiny passages, especially for the pilot jets. Dirty pilot jets would also cause lean idle problems. If you’ve determined that the jets are clean, you may need to change them up a size or two to allow a higher flow of fuel.

Why does my ATV have hot air coming out of it?
This process happens continuously at high speed when the engine is running. Over time, carbon residue may build up on the valve head, making for an un-tight seal. This will allow hot air and flames from the explosion to exit through the gap when the valve is supposed to be completely closed.
