It was midnight here and I seem to have slipped.
I think you could be right about this. Maybe the fat needle jet reverse the effect? Maybe when I get my P6s the behavior will change.This would not be so true if you are rich in the nj/jn combo already-but more likely that when the slide is closing it is richening the mixture and producing more power to pick up speed.
Maybe when I went down to P8 it became possible to use even larger MJ, but then the plugs tell a different story.
Then as strange as it was to reduce down to MJ 185 as strange it is to reduce from Q2 to P6 when others are running Q2s.
The bike is strong in bottom, mid and top so shifting to slightly smaller carbs to gain off pipe performance isn't really interesting, I'd rather shift down and keep her boiling or I'll cruise and then there is still plenty. Compared to MX a 32 for 180cc is rather small. Then I have read that some have had almost zero gain when shifting from 26-32. My motivation was to get a carb with a wide range of tuning options. It may sound funny when I am in the middle of confusion, but it is actually worse to have no alternative needles and needle jets.
