THIS IS A NEW BMW MOTORCYCLE PURCHASED IN JANUARY. AROUND 4000 MILES THE ENGINE STARTED MAKING A METALLIC NOISE AFTER WARMED UP, AND BECAME PROGRESSIVELY WORSE. MOTORCYCLE IS NOW AND HAS BEEN LOCATED AT AUTHORIZED BMW SERVICE REPAIR CENTER FOR ABOUT THREE WEEKS; THE NOISE, TO DATE, HAS NOT BEEN CLEARLY DIAGNOSED, BUT HAS BEEN ACKNOWLEDGED BY REPAIR STAFF THAT NOISE IS ABNORMAL. CONCERN IS THAT ENGINE (POSSIBLY CAM TIMING CHAIN(S)??
