1. Exhaust leak: An exhaust leak can cause the exhaust pipe to get hot because the hot exhaust gases are escaping from the system and coming into contact with the outside air. This can be caused by a damaged exhaust gasket, a loose exhaust clamp, or a hole in the exhaust pipe.
2. Clogged exhaust pipe: A clogged exhaust pipe can also cause the exhaust to get hot because the exhaust gases are not able to flow freely through the system. This can be caused by a build-up of carbon deposits, dirt, or debris in the exhaust pipe.
3. Lean fuel mixture: A lean fuel mixture can also cause the exhaust to get hot because the engine is not getting enough fuel to cool the exhaust gases. This can be caused by a dirty carburetor, a clogged fuel filter, or a vacuum leak.
4. Engine overheating: If the engine is overheating, this can also cause the exhaust to get hot. This can be caused by a variety of factors, such as a low coolant level, a faulty thermostat, or a water pump that is not working properly.
If you notice that one exhaust on your Yamaha Banshee is getting hot, it is important to troubleshoot the problem and fix it as soon as possible to prevent damage to the engine or exhaust system.
