I'm looking to invest in this bike. 1999 Honda Nighthawk CB750, I found it for a really really cheap price. I'm not sure if it's a good thing just yet. I do have the time and patience to work on it I just dont know where to start.

****The owner informed me that the bike has a bad knocking noise in the bottom right portion of the engine and he believe the engine has a bad crank or a thrown piston/rod or both. It maybe have a warped head as well. 36,000 miles****
