Motorcycle with ML serial numbers have been overtorqued steering bearing nuts from factory, multiple problems showing up. Steering on mine locked up in a turn, but was able to force it to straighten out. Kawasaki is aware they overtorqued (via multiple sources) but has not released a tech bulletin, or service recall on a dangerous situation. Slow speeds steering will have a tight bind at the 12" position, and will have a hard time turning left or right out of the tight spot. Occasionally, turning back into the 12 position will cause a bind/catc…

BALANCER IDLER SHAFT, TENSIONER LEVER FAILURE ON A 2001 KAWASAKI KLR 650 MOTORCYCLE, RESULTING IN PIECES OF STEEL ENTERING OIL SUMP, CRANKCASE AND TRANSMISSION OF ENGINE.
CHANGED OIL AND DISCOVERED PIECES OF METAL IN CRANKCASE. HAD A BROKEN IDLER SHAFT LEVER THAT SPLIT IN TWO. LUCKILY IT DID NOT GIVE WAY WHILE I WAS RUNNING AND SEIZE THE ENGINE. DESIGN FLAW IN THE IDLER SHAFT LEVER WELD RESULTED IN FAILURE. *NM
KAWASAKI KLR650 BALANCER TENSIONER AND CAM SPRING ON MOTORCYCLE LESS THAN ONE YEAR OLD WITH LOW MILEAGE. AFTER READING OF SIMILAR FAILURES IN OTHER MOTORCYCLES SOME OF WHICH REPORTEDLY RESULTED IN INJURY, I DECIDED TO OPEN THE ENGINE HOUSING TO INVESTIGATE. BOTH COMPONENTS HAD SHATTERED RESULTING IN METALIC FRAGMENTATION RESIDUE DRAWN INTO THE OIL PUMP MECHANISM (BUT STOPPED BY OIL PUMP METALIC SCREENING).
THE IDLER SHAFT LEVER (AKA "DOOHICKEY") BROKE IN HALF AND THE PIECES OF IT WERE FLOATING AROUND IN THE CRANK CASED. THIS IS VERY DANGEROUS BECAUSE IF A PIECE OF THE IDLER SHAFT LEVER GETS CAUGHT IN THE COUNTERBALANCE CHAIN OR CAUSES A CRANK BEARING FAILURE THE ENGINE COULD LOCK UP AT SPEED CAUSING A CRASH. I REPLACED THE IDLER SHAFT LEVER WITH A STRONGER AFTERMARKET COMPONENT. *TR

CAM CHAIN ADJUSTER OTHERWISE KNOW AS A DOOHICKEY. IF IT FAILS IT MAY CAUSE THE ENGINE TO SEIZE UP WITHOUT WARNING, I CHANGE MINE AFTER IT BROKE BUT DID NOT CAUSE MASSIVE INTERNAL DAMAGE I WAS UNAWARE THAT MINE HAD FAILED I DID THE CHANGE AS PREVENTATIVE MAINTENANCE THIS PROBLEM HAS BEEN KNOWN TO THE KLR COMMUNITY FOR MANY YEARS BUT KAWASAKI REFUSES TO RECOGNIZE IT, DO A GOOGLE SEARCH ON DOOHICKEY FOR MORE INFO

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
