I had been working at a Honda dealer when these came out. From a maintenance standpoint, not an improvement over the single cammers.
Valves would get tight quickly, and many would need valve jobs in 10-12k miles, some under warranty. We didn't know why - same part numbers for valves and guides, shims and buckets as the CBX, which had no problems. Probably cam closing ramps.
Their alternator brushes wore quickly, and if dropped even mildly on the right side, the thin engine cover would distort and the alternator rotor would touch the windings. On the plus side, they were faster, and the new cylinder studs allowed less head gasket failures.
Not a lot of fond memories
