Kev made those "how to remove an engine" instructions for me as I changed the motor on my xt with the help of a friend. I didn't weight the engine on it's own but let me tell you this, with the engine off, I was left with the frame, the fork and the two wheels attached, I could lift the whole bike with one hand effortlessly. It took me and a friend to lift the complete engine to install it!

Ok, I could carry it on its own in a box, squatting carefully to standing position, as I did when I bought it, but it was like a weight lifting competition!! That is where the bike weight is. in the friggin' engine! Damn that engine was heavy. I'll never forget it.
