So - i have changed the clip position back to the middle (3) position and run the bike (air screw out 1 turn). It was still running a bit rough around 1/2 throttle and 5000rpm. I then tried it with the choke open 1/4 and that made a big difference, it was running much better. I also tried it with the choke open 1/2 and then with the air filters off, but this was less successful.
Hopefully this is adding to the picture of the biked issues, maybe someone has an idea how to sort it out?
