I'm just breaking in my scrambler and on a little more than half my plug the coloring is a real dark brown and on the other half it's a real light brown with almost an orange tint. the electrode is all a medium brown. any ideas why it is uneven?

 

I've heard that's common. Mine does the same thing. Sounds like your jetting is close.

 

Oh good I was thinking something might be wrong. what main are you running?

 

The part of the plug that is facing the exhaust will have a little different color to it.This is normal.

 

thanks
