Rick,
Even considering 140# pull on the spring, it is at about a 45 degree angle from the vertical, so the most it offsets is about 70#. I believe ths addition was more to dampen some harmonic vibration than attempt to support the drive unit. I played with the one on my cafe racer increasing and decreasining the 1.5 inch coil length the manual specifies and saw no real affect on handling, but a small difference in transmitted vibration.
