Now, when you say it was the first production safety seat, do you mean it was Yamaha's first? Because my dad's '81 Maico 490 actually has a safety seat. It's the only one I've ever seen on that year of Maico, but apparently it was an option at some point. If it's an aftermarket part, it's the only one on the entire bike. Even the tires are stock from the factory, and have fresh treads. This has been a garage queen since day one.
As for bikes the 'Hunk doesn't like, number one on his list of worst bikes of all time is the infamous Suzuki TM400. However, my uncle happened to have one of those back when they were new, and doesn't recall any of the engine weirdness that Super Chunk claims. The spooky handling, yes, but not the mystical on/off powerband. I suspect that he (my uncle) had one of the TMs that had something done to the ignition, which was said to be the only way to resolve the problem. The only review he really had on the engine was that it was extremely fast when you wanted it to be.
