Just got an idea and had some questions. I live off grid with free natural gas. My NG is free but the well has limits and if I use to large of a generator, it sucks water out of the well and pressure drops. I have an excellent high efficiency inverter charger that handle some pretty huge loads. I don't much care for high rpm generators or even inverter generators because of the possible finicky electronics. I have a 24 volt 300 amp military niehoff alternator. Weighs about 60-70 lbs so I am pretty sure its a true 300 amps continuous. I plan on running it at a lower speed and only using around 140 amps tops. Does anyone know how long a predator 212/420 will last at a lower rpm? I've seen people on youtube saying they have over 3000 hours on the generator so i figure 1800-2000 rpm should be a breeze for the engine. Most likely will be a steady state 1800-2000 rpm. Any modification I can do to help engine life? I may put a K&N filter on it and remove the smog box filter and replace with just a regular filter for it so no nasty crankcase air going in. Extra zinc? 120/300 bucks right now but the long it lasts, the lower the running costs. I might put a big old box fan or blower on it to make it cool. I will remove the gas tank as well since i won't need it. I would prefer pressure lubricated so I could put a external oil cooler with thermostat in and a bypass of some kind. I just can't justify something that expensive though that might not last. v twins costs as much as rebuilt car engines. Most of these modifications can be reused if the engine nukes itself. Thoughts?
