I'm going to take the engine out of my CB750 K1 this week and am trying to decide how. I was wondering if anyone has used a block and tackle from the roof to help lift and support the engine while it is being maneuvered out. If so how and where did you support the engine. If you think this will work OK let me know. Likewise if this is a bad idea I'd like to know as well.
Here are a few more options.
1) Work on your power thrusts, put a back brace on, and go to town.
2) Get a friend to help. This is the way I did it, because we needed to do it quick. Make sure to leave the kickstand on to have something to hold onto. It wasn't that bad...
3) Take the wheels, swing arm, and front forks off. Then lay the frame on its side and unbolt the engine, and lift the frame off the engine. Presto! Be sure to lay down some wood or something, so not too damage any covers. This is more time consuming, but if you're tearing down anyways its super easy.
