The only thing that I could potentially see would be that you are linking the front and rear cylinders. Not knowing how the computer is programmed I don't know if this would screw up any of the Manifold Air Pressure (MAP) sensors, which is how part of the "tuning" of the bike is done. Is it a big problem? Nope. Try it. If it doesn't work then grab a couple of beers and install some block off plates.
