That is a good looking project you have going.
I let my mom's 69 Trailmaster go @ VMD last year. It hadnt run in 10 years. The guy had it running after 2 days of working in his vender area. We still have a blue 75cc with the long tank and seat with low bars. I found it full of water under the eaves of an old house. The motor is solid (one rusted lump) the tank is full of rust.
