I occasionally go out to the garage in the winter and start my motorcycle (Kawasaki Concours C10). I like to hear it and believe its good to get the fluids circulating every so often. I happened to notice extra heat coming out of the vent. I saw that the exhaust header was glowing. This was due to the choke being on.
Of course, I’m a curious guy, so I had to see how hot it actually was!
Over 700 degrees is nuts and probably bad for the engine. I’ll be more careful with the choke in the future!
