There are a few items that I feel were pretty creative that may be small details and hard to see unless it is in person. One example of an item I used in place of buying an aftermarket item is my electronics tank.
I used an expired fire extinguisher to get the desired size I wanted. Both ends were cut off and faced evenly on a lathe. The end caps are bolted in place to a ring that is welded and tapped on the inside of the tube.
All my components that were on my handlebars are also mounted to the tank, example: emergency safety cut off switch and start button.
My sissy bar is an old tiki torch stolen from my neighbors house.
