It should be a brownish color,like a papersack,maybe a shade darker to be safe.Lean will make it whiteish.Your plug may have just been getting weak.Do a wide open plug chop and see what color you get.

if it has a rusty color with rust, i would say your takin on water, if there is rust on it, maybe from ridin in rain, or a gasket and your loosin fluid

run it hard to clean the plug and cylinder out

it should be the color of a hot TAN chick, lol
