YAMAHA Complaints

OIL PUMP DRIVE GEAR FAILURE LED TO 3 COLLAPSED LIFTERS AND SUBSIQUENT ENGINE FAILURE.

THERE WAS A RECALL ISSUED FOR THE SPEEDOMETER LENS, BUT THE DEALER REFUSED TO PAY BECAUSE THE VEHICLE WAS NO LONGER UNDER WARRANTY, THE CONSUMER STATED THE SPEEDOMETER LENS ASSEMBLY WAS REPLACED BEFORE AND WAS PAID BY YAMAHA. THE SPEEDOMETER LENS WAS FOGGED. MR SCC *JB

THE CONSUMER RECEIVED NHTSA RECALL 03V309000 CONCERNING TRANSMISSION FAILURE. THE CONSUMER CONTACTED THE DEALER, WHO INFORMED HIM THAT THE PARTS THAT WERE NEEDED TO REPAIR THE MOTORCYCLE WERE NOT AVAILABLE, AND IT COULD BE SEVERAL MONTHS BEFORE THE PARTS WOULD BE AVAILABLE. *AK THE RECALL WAS DATED FOR 01/09/2004 AND THE RECALL PARTS WERE STILL NOT AVAILABLE. *SC *JB

BATTERY IS LEAKING ON MY NEW BIKE. I HAVE GONE TO NUMEROUS FORUMS AND IT SEEMS LIKE IT IS DOING THE SAME ON THOSE PEOPLES BIKES. WE ALL RIDE THE SAME BIKE AND WE ALL GET THE SAME DAMAGE TO OUR BIKES. *NLM

I HAVE A 2003 YAMAHA GRIZZLY 660. IT HAS A PROBLEM WITH THE FUEL BOILING IN THE CARBURETOR. ONCE IT WARMS UP IT STALLS ESPECIALLY WHEN GOING UPHILL, WHICH COULD EASILY CAUSE IT TO ROLL OVER. I TOOK IT TO THE DEALER, AND THEY TOLD ME THAT YAMAHA WOULD NOT COVER IT ON THE SIX MONTH WARRANTY( I'VE ONLY HAD IT TWO MONTHS). *NLM

BATTERY ACID FROM SEALED BATTERY LEAKING ONTO VITAL COMPONENTS. METAL BREAK DOWN FROM ACID CONTACT. PARTS AFFECTED- DRIVE CHAIN, SWINGARM, REAR SHOCK AND LINKAGE HOLD SHOCK TO SWINGARM. *NLM

STEERING MECHANISM OF MOTORCYCLE LOCKED UPON TURNING TO THE RIGHT, THEN SUBSEQUENTLY LOCKED TO THE LEFT AS WELL, CAUSING A VEHICLE CRASH. *JB

2003 YAMAHA GRIZZLY 660 LE AFTER RIDING FOR ABOUT 3 HOURS I STARTED UP AN INCLINE TO GO HOME. HALFWAY UP THE ATV SPUTTERED, LOST POWER AND ROLLED BACKWARDS BACK DOWN THE HILL. LUCKILY IT WASN'T EXTREMELY LONG OR STEEP SO I WAS ABLE TO CONTROL THE ATV WHILE BACK DOWN. IT APPEARED I HAD THE VAPOR LOCK ISSUE NUMEROURS OTHERS HAD. I INSPECTED VENT LINES FOR CLOGS AND FOUND NONE. I TRIED AGAIN AFTER ABOUT 15 MINUTES AND AGAIN HAD TO BACK DOWN. I WAITED FOR ANOTHER 30 MINUTES TO GIVE IT TIME TO COOL AND TRIED A THIRD TIME. I MADE IT ALMOST TO THE TOP THIS TIME AND IT SPUTTERED AND QUIT. THIS PORTION OF THE INCLINE WAS NOT AS STEEP AND I WAS ABLE TO STOP THE ATV AND USE MY WINCH TO GET TO THE TOP. IT SPUTTERD THE REST OF THE WAY HOME AND WHEN I GOT THERE I COULD HEAR A "BOILING" SOUND IN THE FUEL TANK. WHEN I REMOVED THE CAP THERE WAS SOME PRESSURE IN THE TANK AND I COULD SEE BUBBLES COMING UP FROM THE LEFT SIDE. I TOOK THE GRIZZLY TO MY LOCAL DEALER THE NEXT WEEK. THEY HAD OTHER WITH THE SAME COMPLAINT. THEY INSTALLED A "HEAT KIT" THAT CONSISTS OF (TO MY KNOWLEDGE) VENTILATED SIDE PANELS, A HEAT SHIELD UNDER THE FUEL TANK AND FUEL LINES WRAPPED IN SHIELDING. IN MY OPINION THESE FIXES DO NOT DIRECTLY ADDRESS THE PROBLEM AND THOUGH THEY SEEM TO HELP I'M UNSURE AS TO WHETHER THE PROBLEM IS COMPLETELY SOLVED. MY PERSONAL OPINION IS THAT THE EXHAUST HEADER IS TOO CLOSE TO THE CARBURETOR, REQUIRING EITHER A COATED HEADER TO MINIMIZE HEAT RADIATED DIRECTLY TO THE CARB BOWL OR A REROUTED PIPE.

I HAVE PURCHASED A 2002 YAMAHA GRIZZLY,AND I HAVE A PROBLEM WITH THE GAS BOILING. I HAVE BEEN ON A WEB SITE ATV NATION AND IT SEEMS THAT A LOT OF PEOPLE LIKE ME ARE HAVING THE SAME PROBLEM. IT CUTS OUT, VAPOR LOCKS AND THE GAS IS ACTUALLY BOILING IN THE GAS TANK. TO ME THIS IS A VERY BIG PROBLEM AND NEEDS SOME ATTENTION AS SOON AS POSSIBLE. *NLM

WHILE DRIVING AND WITHOUT WARNING THE VEHICLES REAR STRUTS SNAPPED AND CAUSED THEM TO RUB AGAINST THE REAR TIRE. *NLM
