hey guys would really appreciate Some opinions . My 2013 Gsxr 1000 seems to vibrate excessively at around 5-7 rpm , while riding in any gear or at any speed. I've got new tires , new chain any sprockets . I feel the tank vibrate really bad , all the way through the bars . It's so bad my frame sliders rattled loose . Is this normal , the bike has being down lightly . Has 13000 km well maintained new oil and air filter , aftermarket exhaust . Dose t seem to change . ANY INFO would be greatly appreciated !! Don't need the dealers bullshit opinions thanks gents!
