does my spark plug look healthy
is this what a healthy bike/ plug looks like?
It this slightly overheating? should i use a colder plug?
this is my...boomstick!
Hardly looks disastrous and no, you shouldn't use a colder plug.
rain? whats that!
Assuming the white balance is correct, the ceramic looks a nice healthy tan colour.
How old are these plugs?
Never try tuning your bike with hotter or colder plugs. You could end up burning a hole thru your piston. The plug looks ok to me. They should have a tan colour, but if there is a lot of white colour to it... you are running lean!
