During idle, your motorcycle isn't working hard and is just ticking over. However, the average motorcycle exhaust temperature during idle is still 600-800 degrees Fahrenheit.
When revving the engine, the temperature can reach 1,000°F which is normal. High speeds may cause even higher temperatures.
A red-hot muffler is often caused by a bad air-to-fuel mixture in the engine, which can also lead to sluggish performance, backfiring, and decreased fuel economy. It's best to have a mechanic check and adjust the mixture using specialized tools.
Regularly checking your motorcycle's oil level is crucial to prevent overheating and long-term engine damage. If the bike has low oil levels, it will overheat faster. If you're unsure about checking or topping up the oil, consult the owner's manual. When buying a used motorcycle, get the maintenance record to keep track of its service history and ensure that the oil was changed on schedule.
Low coolant levels can cause a motorcycle exhaust to overheat. Check the owner's manual for the coolant reservoir location and add more coolant if it's low. Use the same type of coolant as the original and consult a mechanic if unsure.
The cooling fan circulates air to keep the engine cool. A faulty fan can cause overheating and damage. Take your motorcycle to a mechanic if you suspect an issue.
If your motorcycle's radiator starts to leak or fails to circulate coolant properly, it can cause the engine to overheat and potentially result in engine damage. It's important to have a mechanic inspect the radiator if you suspect it's failing.
