Spark plug help

Before i had 86 jet and i put 88 jet. Is the sparkplug too rich/lean or okay?

 

This is after 1or 2km

 

looking better its hard to tell with plug so far away . but it does not look on the lean side

 

Thanks, i will try to take a better picture

 

Here we go .....

this is an image of my old spark plug i dragged out of the bin to show you what sort of colour your looking for. as you can see it has a chocolate brown staining or more like a tea brown staining , this is tell you the bike is jetted just right and its not running very lean or overly rich, its just right.
