GSXR'sandall sportbikes are machines...and their engines are 100% complete precision. There should VERY little shavings coming out. They were made to be driven hard. As for the break in period you'll here a difference song and dance from every other yahoo in the world. This is a machine. Keeping it below 7000rpms for 500miles is bull...If you do this, you aren't breaking in the break, due to the obvious that your not using the higher rpms' of the bike. These bikes are made to be rev'd, ripped, and shifted hard. They are machines. As for the first 500 miles, yes go alittle easy but dont baby it. Let it learn itself and work itself. Hit the redline a few times. Let the frame, forks, suspension feel all of its ins and outs that it has. Keeping it easy wont allow the bike to experience what it was made for.
But hey, I'm just another yahoo on a web forum posted my crapola!
