Berg's are new to me so I don't understand them real well yet. I've bought a 2006 550fe. When I bought it we started it and it blew grey smoke and the bloke said that it would clear after a run down the road. Which it did. The problem is now it won't stop blowing smoke and if you put your finger over the engine breather it is sucking air (which I think is strange) and when you stop the engine it sometimes will drop about 5ml of engine oil out the breather. Do you's think I'm up for a rebuild or it is something else. A strange thing he said when I loaded it onto the ute was "even if the head is stuffed and you have to replace it it still works out a cheap bike" So don't know if he knew something or not. Thanks in advance Darcy :unsure:
