Piston color

[802gt500]

I have a 12 gt500 gen 2 id1000s and jdm cams. Changing the plugs last night and noticed 1 piston was very light tan verses the other pistons which were black and covered with carbon. I also noticed 2 other pistons that were cleaner than the other 5. I could actually read the part # on the "clean piston".

Any thougts on this. I was thinking about changing injector location and see if the new location cleans the piston off.

Thanks for any info on this.
