Triumph Tiger 1050 - Engine Pinned at 7000-8000 RPM

Hey guys, Anyone ever had their engine get stuck revving? I was riding along today and all of a sudden the bike just took off. Thankfully no crash as I was on a quite road and pulled the clutch then kill switch. Coasted to a stop and now anytime I start the bike it revs to 7000-8000 RPM and stays there. Throttle rolls as per normal and will still increase revs but engine will not drop below 7000. Opened up the airbox expecting stuck butterflies, but they are not stuck and operate as expected when the throttle is turned. Throttle cable does not seem to be snagged on anything and is not tight. So any ideas?

Bike is a 2008 Tiger 1050 and is coming up on 20,000 miles.

The butterflies are CLOSED and it revs to 7K? ALMOST closed will flow enough air to rev up with no load on the engine...

Are the throttlebodies even in the manifolds. To get that much air something is falling off or drastically cracked.

Looks like it is the gears in the Stepper Motor... A guy in another forum at the exact same issue and that was the cause of his.
