    Black specks that look like pepper in the coolant bottle.

    Coolant level in bottle keeps needing to be filled over time.

    The black specks are pieces of the head gasket that has failed.

    small amounts of milky oil in a catch can is ok. on dipstick or oil fill cap, you got a problem.

    if you think the gasket is blown, look for black flecks in the bottle. you can also take the overflow line off the bottle and run it under seat or somehwhere you can see it while riding and make a wide open pass. if it starts blowing coolant out than it's time to pull the head for a gasket.

    thanks for the help guys, we've got no black specs and the coolant level is stable so i think we are in the clear, taking them out today so we will find out anyway
