[QUOTE="Rednaxs60, post: 226533, member: 4617"] Did additional looking. The 49 state and CA '85/'86 FI models are different from the Canadian versions. These have a secondary air system to meet the state environmental legislation, the Canadian version(s) do not. The 49 state and CA FI models have the IAC system for additional combustion air. The air chamber vacuum and air supply passages in the throttle bodies are different. Checked the air chamber from my bike and the throttle body throats do not have any additional ports for air in/out (?). Have sealed off the potential secondary air passages to mitigate any issues because of these. The cylinder heads are different. The heads for the 49 state and CA FI models have secondary air supply system ports in the top of the head to accept the secondary air supply tubes, the Canadian version(s) do not: [ATTACH]48764[/ATTACH][ATTACH]48765[/ATTACH] This is a pic of the Canadian cylinder head. Notice the absence of the secondary air supply system ports: [ATTACH]48766[/ATTACH] I'm thinking that the secondary air supply system adds air to the exhaust side of the cylinder head, in essence the equivalent of the modern day PAIR system.
