MY 2001 YAMAHA R6 IS LEAKING BATTERY ACID ALL OVER MY SWINGARM, SHOCK, CHAIN AND FOOTREST. YAMAH WILL NOT RECALL THIS DEFECTIVE BATTERY PROBLEM, ALTHOUGH THEY HAVE REDESIGNED THE BATTER WITH THE VENT HOLES IN A DIFFERENT PLACE TO PREVENT THE BATTERY ACID LEAK PROBLEM. THEY ARE HOPING THAT THE PROBLEM WILL OCCUR AFTER THE 1-YEAR WARRANTY IS EXPIRED SO THEY CAN REFUSE TO PAY TO REPLACE THE DAMAGED PARTS AND DEFECTIVE BATTERY. YAMAHA HAS A DESIGN FLAW AND IT SHOULD BE COVERED WHETHER THE WARRANTY HAS EXPIRED OR NOT. A FAULTY DESIGN SHOULD NOT BE A WARRANTY ISSUE, BUT A RECALL ISSUE. MY $8000 MOTORCYCLE WAS IN PERFECT CONDITION AND NOW IT IS RUINED DUE TO THIS PROBLEM, AND MY RESALE VALUE IS SUBSTANTIALLY EFFECTED. *AK

THE BATTERY LEAKED ACID OUT ALL OVER THE SWINGARM, SHOCK, FOOTPEG, AND CHAIN. THE LISTED COMPONENTS ARE RUINED. A DANGEROUS SITUATION EXISTS IN THAT THE CHAIN IS DAMAGED BY THE ACID AND MAY BREAK WHILE IN OPERATION. I CONTACTED YAMAHA AND WAS NOT TREATED WELL AT ALL. THEY SAID IT WAS MY FAULT BECAUSE I LET THE BATTERY DISCHARGE. HOWEVER, THEY HAVE SINCE REDESIGNED THE BATTERY. I HAVE HEARD OF MANY PEOPLE THAT HAVE HAD THIS PROBLEM FIXED BY YAMAHA. THERE IS CLEARLY A SAFETY ISSUE HERE. NLM
