I was riding to work the other dat (at 4 AM) and my engine strated knocking, ppulled off to check it out and the engine died. To make a long story short ended up getting it towed to RMS and they told me I need a whole new engine, parts alone from them would be $6000. I ride a 2007 zx6r and I don't even know where to start sourcing out parts for it. I've poked around online and I think I may be able to purchase parts separately, but I don't even know what I need to buy. I know the head gasket is shot as well as the crankcase, he told me that and said that I should look online to source out a cheaper engine... any suggestions??? Please help I want to ride!!!
