So, I parked my 1978 CB750F (18.5K) for the winter in october. Went through the necessary prep. Changed oil, drained carbs, filled tank + sea foam. The bike was running pretty good last summer. About 3k on it over the warm months. Was leaking a hair of oil above the cylinders... figured it needed new rings maybe? Never really got around to it. So, it's finally a livable state in MN (for the time being) and I've got the bike out twice now. 30 miles. Did the whole change oil and such before I got it out. I noticed today that I'm dripping oil like crazy out of the left side top cylinder. Wondering what the hell happened. I'm wondering if the gasket might have just had it's last winter or if something else could have gone wrong. Anyone have any ideas?
