I bought a Honda 2000 and companion based on watts needed to run the roof air,
weight that an old man could carry, quietness, and brand reputation.
I started buying Yamaha motor cycles in 1969, and owned 6 of them over the next several years. The 4th, 5th, and 6th ones had major manufacturer defects. Two were tuned so poorly, they would not even get me home, and one had a transmission gear
fall in two pieces in the first ten minutes of riding.
That was the end of my love affair with the Yammies. Since then I have owned a dozen or so Hondas. They were much more sorted out tuning wise, and only needed minor jetting changes for altitude. None had any mechanical problems from the factory. They all had remarkable reliability and held their value. I bought a Honda Fit automobile that now has 44000 miles with no repairs of any kind. NONE. It is a solid rattle free car with excellent fit and finish. I will trust Honda until they change their ways.

Yamaha may make perfectly fine generators, but they won't get me to be a guinea pig in their product development any more.
