created a monster
So I followed the fuel curve idea. Started thinking that maybe was a bit fat through the middle (hence the loaded plug, due to clip position) and lean on the top. I figured that this would cause the cases to load up with fuel, then once they cleaned out it would go lean. When I was looking at the needle profiles I posted I found it hard to believe that the N3xx and the NExx were so far apart, but both have a following. Thought that maybe they were both off to either side of what the bike would really like. I took my measurements, a really lean taper old brass needle that I had lying around, chucked it in the lathe, and made the needle labeled "MOD" in the attached chart. I have to say that after a short test rip around town, I'm sold! Installed it on 2nd clip, with 40 pilot and still 165 main (only change 1 thing at a time). The main now shows a touch lean, but other than that it's the crispest thing I have ever ridden! It will pull all gears and wind for minutes in 6th. Also, kudos to the law officer who turned a blind eye to my test.
