Re: Honda GXH50 hp
Technically, that motor is no good for that law. Doesn't matter what you have it governed to, the motor is rated at 2.1 bhp.
Brake horsepower (abbreviated bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump, and other auxiliary components such as alternator, power steering pump, muffled exhaust system, etc.
This means that it doesn't matter about the gears or anything, unfortunately.
Does the motor say 2.1hp on it anywhere? If not, you're probably fine. Even if it does, you're probably ok unless you get stopped by a grumpy cop...2.1 is awfully close to 2. but still....
If it doesn't say 2.1hp on it, you're fine. if it does and you're worried, find a way to take it off without it looking like you just straight up took it off.
