Early A weight
I'll take a guess....the base weight I read somewhere on a 6cyl was 2800lbs.
So if we add 150 for the 273 we got 2950. Take out the seat, tank, heater, lets say -100, 2850. Add for the steel probably, 150lbs., figuring 1 1/2" by 095Fuel cell is a trade off for the tank, so I'd guess right at 3000lbs.
Just a guess...Dave
