The two main air baffles were constructed from parts recieved in the Sonex Jabiru Installation kit. The back wall off each baffle were attached with rivets. Four slots, two on each side, were cut to allow access for the oil accss tubes in between the heads. The baffles were removed and the exhaust side spark plugs were removed for a CHT Probe to be installed. It was quickly found to have interference probles......this will have to be worked on.
