Just picked up an mc21. Its in great shape, but riding it the other day, when I applied the front brake (I was braking moderately hard) there was a definate chatter to the front end. It didn't make the bike uncontrollable, just not smooth like it should be. The front pads are in good shape, it has a stock se front end, and braided lines. Other than the prblem being caused from rotors possibly being bent, is the chattering on the front normal for a 92 NSR? Is that normal for a bike with a non-floating front disks? Cliff
