That engine. Rumor has it that it was designed by Cosworth and, for what it’s worth, I would like to believe it. But it was the look that had me at hello when I first laid eyes on it during the Reagan administration (first term). And it delivered the goods, too: DOHCs, counterbalancer, four-valve-per-cylinder heads, water cooling, dual exhaust ports, and dual downdraft carbs. Uh-oh. Those double-D Mikuni B34s proved to be the Vision’s biggest stumbling point – literally (the ailment is better known as “The Vision Stumble”). The internet is brimming with “fixes,” but it all comes down to installing an upgraded airbox and keeping the carb internals surgery-room clean. Performance improves, but a bit of stumble remains.
