I rigged mine up with data logging O2 sensor, TPS, RPM, CHT now I need the snow and ice to leave so I can ride the thing.
When I did some research as to ideal A:F ratios at different speeds/conditions, the answers were all over the map. Some repeat the old 14.7 and others just say go to around 13:1 for power and 15 for economy.
In reality, the answer is different for each application, but we still need to know what it's doing and then we can plot the answers.
