1983 BMW R80ST Assemble & Install Gas Tank

This “project bike” came with it’s original gas tank. There was a small dent in the tank near the front and scraps and gashes in the paint. The inside red tank lining was in good condition. I had it repaired and repainted. I refurbished the gas cap, put on new BMW roundels, replaced the rear bracket that secures the tank to the spine tube and installed new fuel lines.

Here are some before and after pictures of the gas tank.
