CAMSHAFT CHAIN TENSIONER BECOMES LOOSE, EXCEPTIONALLY LOOSE INCREASING THE CHANCE FOR ENGINE TIMING TO JUMP, SLIP, OR FOR THE CAMSHAFT CHAIN TO BREAK WHILE IN MOTION LEADING TO OR ACCELERATING ENGINE DAMAGE AND WEAR. *TR

DRIVING ACROSS THE INTERSTATE10 SALT RIVER BRIDGE IN PHOENIX AZ, THERE IS A DIP AT ONE OF THE BRIDGE EXPANSION JOINTS. IT IS NOT A VERY SEVERE DIP BUT THE REAR SUSPENSION ON THIS NEW MOTORCYCLE BOUNCED VIOLENTLY 5 TIMES AFTER THIS DIP. THERE IS AN ADJUSTMENT SCREW TO INCREASE THE DAMPING AND I TURNED IT TO THE MAXIMUM VALUE, BOTH FRONT AND REAR, THIS REDUCED THE AMOUNT OF POST BUMP BOUNCING TO AROUND 2 TIMES. THIS IS INADEQUATE SUSPENSION DAMPING AND I BELIEVE IT COULD BE A HAZARD, ESPECIALLY IF IT HAPPENS IN A TURN, WITH AN INEXPERIENCED RIDER. I AM BUYING A DIFFERENT REAR SHOCK FOR THIS MOTORCYCLE, BUT NOT EVERYBODY HAS THAT ABILITY AND A NEW REAR SHOCK IS NOT CHEAP OR EASY TO INSTALL. I AM ALSO CHANGING THE FRONT FORK OIL TO A HIGHER VISCOSITY, TO STOP THE FRONT END FROM OVER RE-BOUNDING. AT THE VERY MINIMUM, I RECOMMEND THAT ALL NEW MOTORCYCLES SHOULD LEAVE THE DEALERSHIPS WITH THE SUSPENSION ADJUSTERS SET TO MAXIMUM VALUE, FRONT AND REAR TO REDUCE THIS PROBLEM. *TR
