So if you want a web page that not only sells the system to convert your Yamaha generator to try fuel system. But awnsers all and every question, such as fuel consumption, warranty issues, ext...
Yamaha Propane and Natural Gas Generators
I did the switch to my EF2800iC...
I found that it ran better, sounds more quiet, works better over 9,000 feet.(live and play in colorado).. The amazing thing is when I change the oil how much cleaner it is... not black like when it ran on gasoline.. also It does not smell as bad as gasoline when running...(it maybe more cleaner, I would myself like to know the question to that)
The sight also sells try fuel generators! knowing what I know now, would never buy just a gasoline generator!
Also one last point I also purchased a remote start system... It is a must with a generator...
As for the do it your selfer... I would rank it 5 out of 10... You do need a drill if you want the try fuel, if you just want propane, you do not need to drill. (do yourself a favor buy a brand new drill bit you only have one shot so you want it sharp, I started with a smaller bit and then redrilled with a larger bit two times... this makes sure the hole stays where i want it and does not bore to one side or the other)
