Sorry if I mis-identified the cable, though Bilgemeaster's photo shows that you are missing something similar.
The E/S switchgear here is a copy of what was fitted to Suzukis of the the period or slightly earlier, only what serves as the decomp lever on your Bullet would, I believe, have been for the carb enrichener/cold start device on the Suzuki. This was an OK swap for the iron barrel Bullet with the old decompressor valve, but as tooseevee rightly points out, it was a terrible idea for the valve lifter on the AVL models.
