I don't know anything about the PT machines but ain’t nothing normal about that picture! Holy Cow!
I do like the fact it has the word HOT on top. Pretty sure if this is normal that would be self explanatory.
If that is a low light picture, it is normal for gasoline engine working at max HP, if that is taken in sunlight, it is not so good.
Retarded ignition will run a red hot exhaust. But there will be other symptoms, like power loss.
These new fangled CCD pocket cameras screw up picture taking big time. Auto exposure on one aspect makes an adjacent detail all color crooked.
