You could always call your motorcycle a golf cart - maybe put some emblems from golf carts on it. For that matter, doesn't Yamaha make golf carts?

That said, my great grandfather passed away when I was a teen. I still regret not asking him more questions. I made it up with his daughter, my grandmother. Oddly enough, the one thing she never mentioned was the great influenza - and I didn't know to ask that question.
