That's the Junk Yard Dog, the motor is a 31cc Zooma. And yes, at one time it was friction drive but I did not like it so I swapped it over to a chain drive. On the right side is the fuel tank, it's off a old gas arc welder.I like the one with the BMX handlebars. What is that motor or kit? It looks like maybe you fabricated the drive. I thought it was a friction drive from the thumbnail, but I see the chain. Is that a lawnmower fuel tank, or a tote box, on the right side?
I run two tanks on the Boxer for added mileage, sometimes I ride very very far and need the extra. There are covers you can purchase to make it look better.I like that fuel tank on the roadmaster, Dave31. The transluscent, plastic tanks look really out of place to me.
