I'm trying to figure out exactly what I have. My bike originally looked like the F1 in the pictures. I was buying stainless brake lines, and the package came with an extra line for an extra brake rotor. Then I started looking at pictures on Google, and found what was supposed to be a '77 but with twin front rotors and comstar wheels. Does anyone know if the first bike pictured is really a '76? Or did the F2 come out halfway through the model year? Or what? And is there a definitive site somewhere that tracks the mods down through the years? Any info appreciated.


and, uh, how do you insert images?
