Outstanding Performance - Difficult Maintenance
on May 27, 2013
Other reviewers are correct: this is relatively quiet and - so far - reliable.
I will focus on the maintenance aspect, which is very important. This generator was not designed with maintenance convenience in mind and you will struggle with it. Based upon the poor design for maintenance purposes, I will probably try a Honda if this needs to be replaced.
- The front and back covers are difficult to reinstall after removing them and the screws used for installation may be easily lost if you allow the cover to pop off once released. A latching mechanism would have been better. Both covers must be removed for full servicing.
- Oil change: get a funnel with a flexible nozzle, the oil has to go in almost horizontally. When draining the oil, a hole is provided in the bottom. Unfortunately, at first, the oil gushes beyond the hole and into the housing.
- Spark plug: a standard ratchet set won't be able to get into this tight fit. Yamaha provides a special toll (because the location is so poorly placed) to remove it. It is not a reliable way to ensure correct tightness.
- Battery: if you think all of the above is hard, wait until you try to access the battery.
All in all, the nightmare of servicing this will cause many users to just ignore it, but it really must be done to ensure proper operation when needed.
UPDATE: couldn't take the extremely poor design of the wheels anymore (it's almost impossible to move this thing around). Bought, on Amazon, the Sparco Folding Platform Truck, 660 lbs., 24-3/4 x 36 x 29-1/2 Inches. The generator fits, perfectly, on this platform. The generator now can be moved around with ease.
