Here is the Woods shaft oiler installed after a slight modification. As supplied it was too tall & hit the bottom of the pipe. I chucked it up in the lathe and cut 1/4" off the top & also used a K&B curved water fitting to maintain clearance. I let Chris Wood know that the oiler needed to be shortened, ideally 3/8", and he said it would still give plenty of lube. They will most likely supply a shorter oiler to anyone who wants to do a rear exhaust motor as I have.
