Defect
IN THE TRANSMISSION ON CERTAIN MOTORCYCLES, THE SECOND/THIRD PINION GEAR MAY BE INCORRECTLY MACHINED WHICH COULD CAUSE ABNORMAL WEAR THAT EVENTUALLY RESULTS IN A BROKEN RETAINER CIRCLIP.
Consequence
IF THE CIRCLIP BREAKS, THE TRANSMISSION COULD LOCK UP, WHICH WOULD ALSO CAUSE THE REAR WHEEL TO LOCK UP. THIS COULD RESULT IN LOSS OF CONTROL AND A CRASH, POSSIBLY RESULTING IN SERIOUS INJURY OR DEATH.
Remedy
YAMAHA WILL REPLACE THE TRANSMISSION GEARS AND SHAFTS WITH NEW ONES. OWNER NOTIFICATION BEGAN ON SEPTEMBER 9, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT YAMAHA AT 1-800-88-YAMAHA OR VISIT THEIR WEBSITE AT WWW.YAMAHA-MOTOR.COM.
