I have a '90 VN750 B2 with 36K on it. Today I was cruising at about 65 mph and I noticed a change in the engine sound. It got louder and sounded like a chain rattling. I pulled over and immediately noticed oil just pouring out of the left lower side of the motor, the clutch housing, along the seam of the case. I shut it off and it dumped all of the oil it had. As I watched the oil stream out of the bike I saw pieces of the gasket falling from the bike too. I have not started it since. Before I crack this thing open, does anyone have any suggestions as to what to look for. It was running beautifully right up until the leak. I had ridden about 30 miles at highway speeds. I am fairly handy with a wrench (adjusted the valves and replaced a timing chain on a KZ750), but I have never worked on this bike other than replacing the final drive last year. Am I going to find terrible things? Any help would be appreciated.
