Back at this thing, with the 02 sensor giving me some data.

At idle, the AFR is 12.5-13.0. The idle quality is good, just richer than I'd like. Does not have the eye burning stink. At light cruse, it's lean. AFR flits around 14.5-15.8 with blips to 16-ish at about 1600-2000 RPM. Lean surging for sure. 2000-3000 is 13s AFR on the primaries. I'm breaking in the new 9" rear and haven't hammered on it yet.

I called BLP and they told me to install .082" T-slot restrictions in the main body. This doesn't seem to jiive with the AFRs I'm seeing. They said lowering the IFRs may help, but to try this first. What do you guys think?
