hey all, i recently noticed my cbr was lurching or surging in lower gears. i put it on the stand and put it in 1st gear. the first thing i noticed was that the chain was jumping. then i heard some rattling in the rear of the engine. pull in the clutch and it goes away. honda dealer says over the phone around 1,800 roughly, to fix. any thoughts? keeping in mind i dont need any dumb comments. i´m %!¤ enough about the whole situation. thanks, steve from ct.
