CB750 / Engine full of fuel and seized up
« on: August 30, 2020, 09:22:42 AM »
Hi all,
I have a CB750K2 which was running fine, I haven't used for a few weeks and when I went to start it yesterday it turned over very slowly then the engine just locked up completely. It is now stuck solid, kickstart or rear wheel in gear won't move it. On investigation i discovered to my horror that I had what seemed like an entire tank of fuel inside the engine! I left the fuel tap on and somehow the carbs leaked into the engine and gearbox rather than come out the overflow. I have drained all the fuel and removed the plugs but the engine is still stock solid. Any ideas of what the damage might be? Is there any thing I can check to narrow it down, not sure I am up to a complete engine removal and strip down?
