Thanks, appreciated.

Those older carbureted bikes ran richer and better, no two ways about it. But they had a lot of Carbon monoxide and unburned fuel in the exhaust.

Interestingly, on the 1100s shipped to Europe, the FI systems were run open loop, and 6% richer than the US Catalytic converter bikes. These bikes are pretty happy at 13.8:1.
