). Anyway lots to learn - bike is not standard but appears to have "in period" mods; non-standard "mag" wheels, Marshall six into one exhaust, aftermarket swing arm(?) and twin pot front brake calipers. I've only been for a quick blast, because the tyres are seriously old (last taxed in 2005) and I want to swap them for some sticky modern covers before venturing out into the cold UK winter, but boy does that exhaust howl!.
I'll try and get some photo's loaded up so the wise can advise on the identity of the mods. Not sure what direction I'm going to go in - ride her for a while as-is first?
I am not quite sure when double-piston brakes were introduced, perhaps it was with the 80 model, perhaps it was only later. My 79 CB1 has front single-piston breakes -- this is original, I know -- and I am just upgrading to double-piston brakes because I find this safer.
