In my opinion that is a parts bike at best. With no title, missing the tank, seat, and carburators, and maybe more, it's not going to be an easy or cheap fix up. Carburetors being gone for years probably mean the intake valves are rusted in place and the open cylinder could have sat with water in in for years. No more than a hundred bucks. You can get that or more out of the cam, cam drive and tach if its present. They are sought after.
