NHTSA Complaint #10166197 — 2006 YAMAHA FZ6

STICKY VALVES ON YAMAHA MOTORCYCLES,THERE HAVE BEEN NUMEROUS REPORTS OF ENGINES LOCKING UP AND STALLING . I QUESTIONED MY DEALER AND HE DOESN'T KNOW ANYTHING ABOUT IT [ SUPPOSEDLY ] I WANT IT ON THE RECORD IN CASE OF AN ACCIDENT . IT HASN'T HAPPENED YET BUT YAMAHA IS AWARE OF THE PROBLEM AND IT SHOULD BE RECTIFIED BEFORE A SERIOUS INJURY OCCURS . THE VALVE SPRINGS ARE TOO WEAK AND SHOULD BE REPLACED , THE RESULTING CARBON BUILD UP CAUSES THE ENGINE TO STALL AND SPIT FIRE OUT OF THE EXHAUST . THIS PROBLEM SHOULD BE ADDRESSED NOW BEFORE AN ACCIDENT HAPPENS . I THINK A RECALL IS IN ORDER THIS IS A 2006 ROAD STAR MIDNIGHT SILVERADO SO IGNORE LATER REFERENCE TO VEHICLE TYPE LATER IN THIS COMPLAINT . I WANT PEACE OF MIND AND WOULD LIKE THIS PROBLEM SOLVED BEFORE INJURY OR POSSIBLE DEATH. *NM
