Almost forgot. I have not finished!. The whole idea behind this project was to solve the problem of going too lean when going quickly to wide open throttle. That is the purpose of the secondary throttle plates.
Now the bike is tuned I have enabled the secondary plates and they seem to behaving exactly as predicted. In addition of preventing it from going lean at WOT, when the plates are partially closed the air velocity increases.
