Great Japanese Build Quality
This generator is huge/heavy but very well made. It is noisy when in operation, nosier than I expected. The included wheel kit is very difficult to install going by included instructions. It came with a defective, from the factory, NGK spark plug, that I replaced for $5. As stated in the description no battery is included, the manual says 12v/30ah or 40ah battery. The included battery cable hookups (automotive style but smaller round) do not fit any battery I could find. Yamaha USA was no... more

Generator
Quiet, well-made, and easy to operate. Packaging and delivery were very good. Wheels are difficult to install; but once installed, the generator moves without much effort.

Love The Generator
Have not had a chance to give it the full test, but it will handle our guest cottage. We were without power for almost 6 days with no running water. Thank God we live on a lake and could take lake baths.

The only disappointment was the advertised free shipping. Generators Direct had a $50 shipping charge added to my credit card. No big deal, but not as advertised.

So Far So Good
I have used the generator once for an event lasting 8 hours. It worked flawlessly supplying 60Amps of power. Only comment I have is that I had to leave the event after 6 hours, run to a gas station and bring back more gasoline. On full load, it only runs for about 6 hours on a full tank.
