AARC, I’ve never heard of an EU2000i breaking a timing belt or camshaft. Probably needs overhauled by the time it needs belt replaced.
I’ve got great confidence in Honda engineers in the design aspect and their quality control seems pretty dang good.
We have a Honda 500EM generator that finally gave up the ghost after 40 years of reliable service.
Reviews and spec sheets aside, real world reputation based on long term use is what I rely upon.
I bet the Yamaha generator is a fine piece of equipment.
500 hours?! I put 500 hours on my generator in the first 6 months and that was a couple years ago. It’s still brand new. Just keep the oil and fuel fresh. They are pretty good at sticking to what works rather than getting caught up in fancy bells and whistles. It would be awesome to schedule run times with my smart phone...but that’s something else to break. I’ve no complaints about the fuel run times.
That IS just my opinion. Your results may vary.
Back to the topic...I would not hesitate to buy a used Honda as long as it looked like it was taken care of. In fact, I’d be looking for one that wouldn’t run due to the fuel spoiling....get a good deal and easily fixed. That goes for just about any generator.
