I had one too an '83 A reg in black. I can even remember the reg A348LVS. I got pissed off with cycling to work so bought it off my brothers mate with 600 miles on it in early '84, I was one of the first lot to have to have a 125cc.
It's the only bike I have ever had from new, had to run it in, I don't think I managed it for long before hitting the power band for the first time, felt like a missile after riding a ratty gs125.
