[QUOTE="ossagp, post: 184287, member: 1650"] Sometimes when you see that parttern on the piston it is due to the transmission starting to bleed some oil into the crankcase, but only if it is a lubricant with a pretty high ratio of detergents. ATF and most multiweights have that righer ratio. One that starts running rich will do it to, especially if the owner makes a swtich to a different oil thinking he is going to make his bike run better. Something with more solvent in it, will clean off some established carbon. [/QUOTE]
