    G'day fella's, I'm new around here and was wondering if someone could shed some light on an issue I think I might have.
    I drained the coolant on my '11 WR300 and pulled the head off and found the ports still half full of coolant! I moved the bike side to side and it still didn't drain.
    I have since pulled the exhaust valve and barrel apart (even when removed it still holds the fluid) to find if anything was blocking the passages but couldn't find anything obvious.

    Is this a problem or is there supposed to be some coolant left in the galleries when you drain the whole system? Do I need to think about modifying/replacing my barrel?

    Did you drain it by just removing the hoses, or did you remove the drain screw from the water pump cover, too?

    I have done both, I actually have the barrel removed at the moment and the coolant is still sitting in the galleries.
