I built this last summer, but it's more than just an occ chopper with an 80 c.c. motor bolted to it. I made a lot of the parts, and modified/customized parts from other bikes to make it all work. The gas tank is from a jesse james chopper and it's fully functional. I smoothed out and re-shaped the front of the tank, and painted it with metallic black laquer with clear laquer over it. I made the exhaust, the carb stack, the gas cap and the hidden chain tensioner. I bought the engine mount but I modified it slightly.
