Here's a couple of pics of my bike. The only difference now is that I changed sprockets from the picture. I went from 50t sprocket to 40t and removed that back stock chain tensioner.
It's a cheap Walmart Huffy but I wanted to see if I could build one of these and make it run before I tried this with an expensive bike.
I can, so the next one will be a really nice bike. I added brakes, changed the handlebar, tensioner, muffler and sprocket and got rid of the rag joint.
