okay i just baught a 02 400ex off a buddy of mine. he cracked the oil tank and put a new one on. well i dunno what he did but i just went to change my oil after i baught it and it has 3/4 of a quart in it and its supposed to be almost 2. and the the oil is black and it smells burnt. exhaust smoke when its cold and u can see a little smoke when u rev it up and it gets to high rpm.... what could all this be??
