Questions to ask yourself before starting any project:
How will I benefit from this?
Do I have a plan?
Do I have the know-how?
Do I have the skill?
Do I have the money to fund this project?
Do I have the time and space?
Do I have the discipline to see this project to fruition, throughout its trials and tribulations?
Will something else in my life hinder or obstruct my success in completing this project?
BTW, how far did you get on your V-twin project?
Did you get past the planning stage?
I benefit from this by reducing the amount of hardware required to put power into my gears.
I have no plan.
My father has the know how.
I have the skill.
It won't take much money for the hardware.
I have more time than I know what to do with, and plenty of space.
Maybe not the discipline, but certainly the will.
There will always be something in life that hinders progress.
I have not gotten past the planning stage, because I still need to get components, materials, and equipment. That in itself will take a while, so I put that on the back burner until I have the ability and contacts to have the tubing made and the components fabricated. The chain, derailleur, freewheels, chainrings, and cassette will be possibly the most expensive parts as they must be made by someone who fabricates them, such as shimano or SRAM. If I attempt to make these components myself, I will be looking at certain failure and injury. However, the frame will be made by me and stress tested to DOT standards. I plan on the frame being salvageable in any crash not involving intense heat, such as combusting fuel. Engines, forks, wheels, and other components can be replaced rather easily. Not so with a frame of this design, the tubes being three times larger and thicker than a standard motorcycle frame and being made of airframe aluminum.
