Yes...it would be about 6" longer. And yes, there are a couple of things you need to work around up there. The aluminum will need to be notched out, ground out or whatever to clear the two square parts of the tunnel/bulk head that stick down. You also need to notch out for the fuel pump mount and there may be a rivet or two that will hit off to the side of the aluminum. Just grind or notch out the aluminum and make it fit nice then rivet it all in from the top nice & tight. You do realize you need to remove the seat, gas tank and air box to do this?
