I followed the last part of the link and got this but not sure if it's the correct picture - http://i268.photobucket.com/albums/jj38/...1.jpg.html if it is then the vent pipe and the electrics get tucked in a channel in the sprocket cover so they are out of the way.
Just took a photo to show the pipes etc running through the sprocket cover channel.
