Ryan must have cut it... Mine came stock with a one piece. The BME 105 in mine fits inside the cowl with no cutouts for the plugs. It is a great combination, but if I was going to buy a new motor for this plane is would have to be a 110 extreme. It is only like $50 more than the 105 with a pretty good power increase. Not that the 105 is a slouch by any means, but the 110 has an amazing power to weight ratio. I had no problems getting mine to balance with the 105, and that is a super light engine too.
