Great job. It looks like your bike is bottoming out at the launch. Mine was set to 3" drop and upon launch the tire was rubbing the inner fender. I have the tiger undertale. When it happened, it would shave 3 mph off.
With us "heavier" riders, it seems the bikes need a good bit of gearing to avoid bogging. Like I said, it would bogg with 16/42, but when I bumped to 16/45 it was almost seemless.
