on the dyno run, there was some black smoke, but not much (see the video, but note that the wall behind the dyno is already stained with soot). I have since given it another 1/4 turn in on the fuel screw.
Last night I did a very long (3rd, then 4th gear) pull at full throttle. I happily noted the EGT didnt see over 620C, so thats pretty good. I imagine on the dyno it would have been similar or less.
