The nearest dyno, as far as I can find out, is some 300 - 400 miles from here so I haven't had it on one. There is a big phone company junction box about 1/8 mile down the paved road that intersects my road at the end of my horse pasture. I have been using that for a marker to run some acceleration tests. The triumph is going about 8 mph faster (allowing for error) than the 88 inch Lowrider the OL had, (probably had something to do with her trading it in on a new Roadking). It was about equal to my 96 inch Night Train until I upgraded it.
I haven't been able to detect any variation in the power delivery that might be caused by low end leanness. Other bikes with similar mods have been run on a dyno and mine feels like it is following pretty much the same torque curve. Flat as a pancake just like stock to around 3400 - 3600, then the slides open and the torque starts angling upward. The effect is about like the turbo coming on in a Cummins Dodge, it goes real good, then starts going even better.
