This afternoon I decided to measure the tapers of the needles I've picked up over the past few weeks.

I discovered the foam in my micrometer box had pretty much crumbled and managed to attach to the tool. I didn't feel like cleaning it so i used a cheap dial caliper. I then plotted them. I'm pretty sure the tapers are constant so I also made a smoothed version. See the the attached for the plots.

The picture pretty much tells the story. The stock needles are pretty rich which I suspect could be the cause of my flat spot. I plan to start with the JHA A25A needle.

Probably not gonna do much on bike for next few weeks. Next weekend I will be in Austin for the motoGP.
