Now I noticed a couple of things. Below the three measurements in digits. Looking at the AFR during the two runs on the freeway (+100km/u) it shows an average of 14,53 AFR between 4000 and 5600 RPM. Between 800 and 4000 RPM it shows an average of 13,2 AFR, a bit richer. Above 6400 RPM it's around 15,35 AFR, a bit leaner.

The measurements off freeway (50-100 km/u) gives slightly different results. Now it shows an average of 13,65 AFR between 4000 and 5600 RPM. Between 800 and 4000 RPM it shows an average of 13,56 AFR. Didn't go above 6400 RPM off freeway.

Conclusion so far is that it is only running stoichiometric on the freeway between 4000 and 5600 rpm. This should be at the time the mains are functioning 100% and the idle jet isn't activated. On the other hand it's a bit rich below 4000 rpm. Also it feels lazy when going from low to higher revs. Doesn't react instantly on the throttle..

Like to hear any suggestions where to go from here.

Gents, in the last couple of days I've tried different setups. Got back to idle 65 main 145 and AC 170. Below you can see the result. Rather rich overal with some stumble around 3k. Surprisingly the engine reacts a lot better than the 56/165/185..
Due to the bike response it seems I'm on the right path here. Changing the idle doesn't make a lot of sense as the AFR is rich overall.. I was wondering what should happen if I only adjusted the AC. Theoreticly it should give air during idleing and in higher revs. Below the setting 65/145/175. The AFR is a bit leaner then with the 170 AC's:
This morning I tried 60/145/175. I have to say that the bike is stonecold during the testlap, while the two above were done with a hot engine. The rich stumble at 3k is allmost gone. Maybe when driving it really warmed up, it wouldn't be noticable at all.
To be continued..!
