I'm glad you said that method was fine Glen as that's how I got the lump out of the Mongrel. Once the pipes, carbs and electrics were off, it took me 20 minutes to undo the engine mounts and lay it on its side and then stand the bike back up and she was out. I did it all alone until wifey helped me lay it down.
Works a treat.
The method they used is fine, it's a pretty common way to remove and install engines. However, to have three of them dick around for soooo long and still have trouble trying to work it out was entertaining.
