2002 KAWASAKI KLR650 Engine And Engine Cooling Problems

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...

DT: THE CONTACT STATED THE ENGINE COUNTER BALANCE PART ON MOTORCYCLE FAILED. THE CONTACT PURCHASED AN AFTER MARKET PART AND REPLACED THE FAILED ONE AT HIS OWN EXPENSE. THE MOTORCYCLE WAS NOT SEEN BY A DEALER. *AK

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

BALANCER IDLE CHAIN ADJUSTER FAILED WHILE DRIVING THE MOTORCYCLE. DEALER NOTIFIED. *AK

THE BALANCER IDLER SHAFT TENSIONING SPRONG WAS DISCOVERED TO BE BROKEN WHEN PREVENTIVE MAINTENANCE WAS CARRIED OUT ON MY 2002 KAWASAKI KLR 650 MOTORCYCLE AT 2867 MILES. POTENTIALLY, THIS FAILURE COULD HAVE CAUSED THE ENGINE TO SIEZE WHILST IN OPERATION.
