In order to do so, the bags and seat were taken off, the main-fuse was unplugged, and the shock lines were disconnected.

  • Drop Seat Kit Battery Box
    8. The stock battery box was removed to make room for the new subframe, and then Alan located the TSM loom (on the right side of the bike) and cut into the insulation to make it longer. It was then wrapped with electrical tape and rerouted to the left side of the bike to where the TSM's new home will be. Also, the new battery cables were installed at this time and hooked up once the battery was installed.

  • Drop Seat Kit Reinstalled Battery
    14. Agent Alan re-installed the battery and hooked up the new cables, then mounted the new fuse box mount onto the subframe, and hooked the coil back up. The battery's cables are longer to make up for the extra length they have to travel due to the relocation of the battery. Also, the cables secure to the sides of each terminal, instead of on the top of the terminals (arrow).

    17. We had Gary sit on the bike again and we took some final measurements. The proof is in the pudding, and FBI's new Drop Seat Kit dropped the bike's height 3 inches. The stock measurement came in at roughly 27 inches from the ground up to the seat. With FBI's kit installed, we measured 24 inches from the ground up to the new seat.
