I am replacing my '86 750 motor this weekend, and had one question. At the shop from which I am purchasing the motor, they have done a compression test, and drained the oil to check for metal. Obviously, the best thing is a leakdown test, but will a compression test detect oil consumption. I ask because I once rebuilt a GPZ750, and although the compression was restored after the rebuild, it still burned oil like a champ. Any experience with these matters?
