One kind of cool feature that Neil, owner of American Thunder next door to my shop, put in is a "burn out pit." The idea was to add some entertainment during special events, but it turns out it is a pretty safe alternative for doing a little "break in" run on a drag bike.
The following video (Jane's first try at video with her digital camera) shows the Knuckledragger on its second time off the rollers. After the previous start up, I leaned the carbs out a bunch, but it is still way rich in the video.
From here it is time to jump back to present day technology and get the Knuckledragger onto a dyno, which will shorten up the tuning process considerably, saving a load of wear and tear on the motor.
