I recently bought an 04 busa with 10,000 miles on it. It still had the original tire believe it or not. Needless to say it needed a new one bad. I had a new 200/50 Bridgestone bt14 so on it went. Now I seem to hear a clicking noise when I take off and I think it is the rear tire hitting the chain. Has anyone had this problem and should I be worried about it? I'm thinking maybe at higher speeds the tire narrows and the chain tightens so it's not rubbing. But I'm not sure because past about 25mph all I can hear is wind. Let me know what you think.
