Did quite the service on my old 1982 Suzuki GSX400F. Replaced all gaskets in the engine, while doing so the cylinders were removed and inspected, as the pistons and rings. The valves got ground and adjusted, valve seals replaced and everything got cleaned good. Also the sump was cleaned, oil filter replaced, carbs cleaned good and so on.
This video shows the first attempt to start after getting it all back together, and all attempts until it finally started running fairly good.
