I didn't care for the fork anti-dive that was activated by the front brake. And you are correct Sir in stating that the Honda V-4 make glorious noises!
I ran the same engine (Ferris mower) on 100LL. It's plentiful here and I have had to replace burned exhaust valves twice! Pump gas only now. Oh, and everything looks good with a synthetic 5w30 in the SW Florida heat.
