Hi Jake,
Yes, I remember the Fulmar. It was a pretty little British lightweight at a time when generally they were very ordinary particularly when compared to the Japanese bikes on the market at the same time.
Nowadays, with a few modern upgrades to the electrics and unleaded petrol a bike like the Fulmar can be a very sweet little jigger. I have seen photos of one fitted with a full width Honda drum brake on the front which both improved the braking no end and made it look even better.
As you can guess, the various mods I mention cure most of the nasties that British lightweights suffered from. Pity the factory didn't do it when they were new. Personally, at the time you speak of I'd seen the light and bought a Suzuki M15. It was a real eye opener.
Cheers,
