High Speed Miss

I'm new to the forum, so if I posted my question in the wrong area I apologize. I have a 2009 Rhino 700 efi. It runs great until 65 kph then it develops a miss. If I push the gas petal down to max (WOT) it misses worse. Anyone experience this problem? What's the fix?

After spending hours testing components and troubleshooting the fuel and electrical system, I decided to call Yamaha and seek advise from their Technicians. It turns out Yamaha has seen fit to build in an electronic governor that will not allow the machine to exceed 65 k/hr or 40 m/hr. The thing that pisses me off the most is the operator's manual and the service manual mentions nothing about an electronic governor. Also when I called the place I purchased the rhino from and told their Technician about the problem I was having, he said it could be this or it could be that, but not once did he say, "oh it's top speed is only 65 k/hr." So now I need to buy a new ECM to increase the top speed, $275 bucks.
