Raptor 700R not starting

Yamaha YFM700R Raptor (2006-Present) - Yamaha ATV Forum - www.bluetraxx.com
First off I have a bit of DIY mechanical experience and I am an aircraft electrician by trade. My wife has a 2007 Yamaha 700R that was in great condition and functioned perfectly but it sat in a garage for a couple of years and now will not start. I'm guessing that the fuel is garbage now. The battery was toast. I replaced the battery and now it cranks but will not start. I siphoned most of the gas out of the tank and replaced with "ethanol free" gas and added about a quarter bottle of Sea Foam (highly recommended on a lot of forums to unclog fuel injectors). I tried to start it again and its the same thing. Will not start. I replaced the spark plug which looked pretty bad. I also read for voltage at the end of the spark plug wire. I put the red lead into the end of the wire and the other end to a large bolt on the frame. I have a constant 10-12V even when not cranking. It never changes. Am I reading it correctly? Is this normal? Let me know if anyone has any suggestions of other things to try before I load this thing up and take it to the local Yamaha shop. Thanks.
