I have question. I just got a 1981 CB750 custom. It will start and ride but when it sits there at idle and gets hot, oil starts to come out of front of engine. I can't tell where its coming from because its inside the (i dont know what they are called exactly) slots on the engine. Does this sound like a cracked block, gasket or? As i said it only does it when i let it sit there and get hot... When i'm riding it and I crack on it, it sputters but if i just ease into it, it runs fine. Can anyone give me some pointers. I got the bike for $800, did I get ripped?
