2005 YAMAHA WARRIOR Engine And Engine Coolingenginegasoline Problems

THESE ARE EXCERPTS FROM THE LETTER THAT I SENT TO YAMAHA ON JAN 15TH, 2006: THE VALVES BEGAN STICKING ON THE ENGINE, RESULTING IN SEVERE POWER LOSS AND MAKING THE BIKE DIFFICULT AND DANGEROUS TO DRIVE. I TRANSPORTED THE BIKE BACK TO SYLACAUGA ON NOV 15TH, AND EXPLAINED TO THE SERVICE MANAGER THE SYMPTOMS. I ALSO TOLD HIM THAT BASED ON WHAT I HAD EXPERIENCED, THAT I WAS FAIRLY CERTAIN THAT IT WAS THE EXHAUST VALVES THAT WERE STICKING'.. HE SAID THAT THEY WOULD TAKE A LOOK AT THE BIKE. ON DECEMBER 13TH, 29 DAYS LATER, HE CALLED TO SAY THAT THE BIKE WAS READY. HE CLAIMED THAT MY IGNITION MODULE WAS FAULTY, AND HAD BURNED OUT MY FUEL PUMP. HE REPLACED THE FUEL PUMP AND THE IGNITION MODULE WITH A SPEEDSTAR UNIT, AND CHARGED ME NOTHING. HE ALSO REPLACED THE SPARK PLUGS, CLAIMING THAT THEY WERE THE WRONG ONES....
