In the race setup I did 300km finally. Average consumption was 6.2L/100km.
Yesterday I put in the O2 sensor again.
The bike has now a smoother behavior and is not so brutal rough anymore. The power is slightly less but not significant and rev up takes a little bit longer..
But all still a happy performance.
The remarkable thing is that after two gas fillings the consumption dropped significantly to max 4.5L / 100km even on ambitious riding style. I ran it for 100km on the expressway stable at 100kmph and got the to 4L / 100km.
I will keep this configuration
