I have experience with a champion open frame 3500/4000 watt generator.
There are 2 approaches to the conversion. One is a carb modification. The other is an adapter between the the carb and the air filter.
With both approaches, I had about a 30 percent power loss (21 amps vs 29 amps - or somewhere in that range) with natural gas (propane may be somewhat better). I also lost some motor surge capability - could start a gas drier with gasoline but not natural gas.
For what it's worth a Champion 2000i cannot start that drier on gasoline either.
With the adapter, I could not get it to run right with gasoline. I had to remove the adapter or else it had no power. Changing from the adapter to the modified carb approach fixed that problem.
US Carb claims no power loss between gasoline and propane/natural gas but I have still been unable to get the open frame generator to perform the same as with gasoline. There's a chance the problem is on my end with the natural gas supply, but given that I've tapped the gas line within a few feet of the meter and no other gas appliances are running when testing I doubt it.
I guess it's possible that the Honda will be different, but if it's not you need to consider whether you'll be happy with closer to 1,100 vs the 1,600 you get with gasoline.
