Just pulled the plugs to see what's going on in there, doesn't look bad but any idea why only a fraction of each plug is burned?

nice color..real good.
I'd guess spark plug position and rotor sweep.
But there is nothing wrong with those plugs

 

Those look awesome!

 

Plugs look fine. The black side is probably on the bottom when installed on the engine. Most likely it's where a little fuel settles inside the spark plug hole. Puddle of fuel doesn't burn completely, so you make carbon. Again, nothing out of the ordinary.

 

hey there what plugs are you using seems like the works pretty fine.

Thanks guys answered my question makes sense when thought of that way
Plugs are the same as stock NGKs 7 and 9

 

Mines are mostly black. Does that mean its running rich?
