Looks great to me.Look at the insulator not the electrodes.Looks tan to me.Should use a new plug though when your doing checks.

is it ok to be rich. i heard that if you are to rich the gas can actualy wash the oil off the sleeve

the plug was new i did a few hours of riding on it

Looks pretty good to me.

I usually run mine a little richer where the insulator is just shy of being black.If excessively rich you can wash oil from sleeve and cause damage.Another sign of being too rich is oil smelling like gas at oil changes.Another map to try is the terminator.Don't be afraid to play around with the flowrate & offset settings,but always start with parameters recomending with maps.Another thing to pay attention for is if the engine wants to run hot than would mean lean.Good luck looks like you're on the right track.
