2002 Kawasaki KLR650

I OWN A 2002 KAWASAKI KLR650 WITH APPROXIMATELY 9500 MILES ON IT. I WAS RIDING AT LOW SPEED ON THE DATE BELOW WHEN I HEARD A LOUD METAL CLANG IN THE ENGINE AND THE MOTORCYCLE CAME TO A SCREECHING HALT. LUCKILY, I WAS ONLY TRAVELING AT 30 MPH AND I WAS NOT IN TRAFFIC. THE CAUSE OF THE INCIDENT WAS NOT IMMEDIATELY KNOWN. WHEN I BROUGHT THE MOTORCYCLE INTO THE REPAIR SHOP, I OBSERVED AFTER THE ENGINE WAS OPENED THAT THE IDLER SHAFT LEVER , A WELDED PIECE OF STEEL, SNAPPED IN HALF, SENDING BOTH BROKEN PIECES INTO THE LOWER END OF ENGINE, AND DISLODGING THE BALANCER CHAIN FROM THE SPROCKET, WHICH CAUSED NEAR-CATASTROPHIC DAMAGE TO THE ENGINE. AFTER SIGNIFICANT TIME AND FINANCIAL INVESTMENT, 40% OF THE TOTAL VALUE OF THE MOTORCYCLE, IT WAS PUT BACK ON THE ROAD HAVING BEEN REPAIRED WITH ONLY KAWASAKI FACTORY PARTS AND RAN FINE FOR A TIME. ABOUT 2000 MILES LATER, I WAS DOING ROUTINE MAINTENANCE WHEN I NOTICED A PIECE OF METAL ATTACHED TO THE MAGNETIC OIL PLUG. AFTER SOME INVESTIGATION I FOUND THIS TO BE A PIECE OF THE NEWLY INSTALLED IDLER SHAFT LEVER. ONCE AGAIN THE PIECE NEEDED TO BE REPLACED. HAD I NOT INSTALLED A MAGNETIC OIL PLUG ANOTHER MAJOR PROBLEM MOST DEFINITELY WOULD HAVE OCCURRED.*AK

KAWASAKI KLR650'S HAVE A PROBLEM WITH AN ENGINE BALANCER LEVER BREAKING. I HAVE A 2002 KLR AND FOUND MY LEVER TO BE BROKEN IN THREE PLACES. ALTHOUGH IT DID NOT CAUSE A CRASH IN THIS CASE, THE BROKEN PIECES COULD EASILY CAUSE AN ACCIDENT (AND HAVE IN THE PAST). YOU CERTAINLY DO NOT WANT THIS PIECE TO BREAK WHILE YOU ON THE HIGH WAY. IT IS WELL KNOWN THAT NEW KLR OWNERS CHANGE THIS PART OUT WITH AN AFTER MARKET PART TO AVOID INJURY. *JB

BALANCER TENSIONER SPRING FAILED. I HAD READ REPORTS ON THE INTERNET DESCTIBING THE BALANCER TENSIONER SYSTEM AS BEING PRONE TO FAILURE. I FOUND THAT THE TENSIONER SPRING HAD BROKEN WHERE IT ATTACHES TO THE ENGINE CASE. THE MOTORCYCLE HAS 6706 MILES ON IT. I AM REPLACING THE SPRING AND TENSION ADJUSTER WITH AN IMPROVED AFTERMARKET KIT. THE FAILURE WAS FOUND BEFORE THERE WAS ANY MAJOR DAMAGE TO THE ENGINE.*AK

SUBJECT: 2002 KAWASAKI KLR650. NOVEMBER 2003, 16,500+ MILES: DAVIS SERVICE CENTER, MONTROSE, COLORADO, WAS ASKED TO REPLACE THE STOCK COUNTERBALANCER CHAIN TENSIONER LEVER WITH A STAINLESS STEEL UPGRADE FROM EAGLE MANUFACTURING & ENGINEERING. THIS WAS TO BE PREVENTIVE MAINTENANCE SINCE I'VE HEARD FROM THAT THIS IS A WEAK POINT. UPON INTERNAL INSPECTION, THE STOCK COUNTER BALANCED CHAIN TENSIONER LEVER WAS FOUND TO BE BROKEN. A BROKEN PIECE HAD GOTTEN INTO THE TRANSMISSION MAIN SHAFT BEARING AND DESTROYED THE RACE/BEARING-HOLDER. THE BEARINGS WERE STILL MORE-OR-LESS IN PLACE AND THIS PROBLEM WAS NOT YET APPARENT WHEN OPERATING THE KLR. SUBSEQUENT CATASTROPHIC FAILURE WAS A DISTINCT POSSIBILITY. FAILURE COULD RESULT IN ENGINE SEIZURE AND SERIOUS HARM TO THE OPERATOR. FROM MY EXPERIENCE ON A KLR650 EMAIL FORUM, I'VE LEARNED THAT THIS PROBLEM OCCURS FREQUENTLY AND THAT KAWASAKI IS AWARE OF IT. *LA
