Revving up and running rich sounds like the choke circuit has developed a mind of its own. Also the float height might be malajusted. If the original 9mm was on the lean side (article below), a previous owner might have over-enriched it. As well as timing problems, leaky exhaust headers can cause backfires. If the exhaust have been off, you'll probably have to put im new gaskets Pretty cheap and resemble big oil drain plug crush seal washers. This was the era when Honda used their customers as factory testers. They didn't clean up their act until the VFR750 came out, after which they never looked back Finally, I'm not certain if you were riding the thing, or just running it static. Unless you were in motion, any bike engine would get wery sulky and overheated if it ran for 10 minutes without proper cooling airflow. And if I recall correctly, the carbs are buried between the Vee, which would be a hellish environment after 10 min static running.
Always was a bit of an overcomplicated dog, although personally, I liked the styling. Problems with camchains, valve clearances, valves, unhardened cam lobes which would pit and destroy the followers, inadequate oil feeds and psychotic carburation.
