I OWN A 2002 YAMAHA ROAD STAR WARRIOR. THE FUEL "QUICK DISCONNECTS" ARE IN MY OPINION, DESIGNED & ENGINEERED VERY POORLY. THEY VIBRATE OFF THE SEAT. THEY HAVE NEVER LEAKED FUEL, THE LOCKING TAB MAKES IT STAY LOCKED SO IT WON'T LEAK. HOWEVER, WHEN IT IS AGAINST THE LOCKING TAB, IT MOVES OFF ITS SEAT ABOUT 3/16" AND RESULTS IN NO FUEL FLOW FROM THE UPPER TANK TO THE LOWER TANK WHERE THE ELECTRIC FUEL PUMP IS. THAT RESULTS IN A "STALL" SITUATION. I WAS SITTING AT A RED LIGHT WAITING FOR IT TO TURN GREEN, I STARTED OUT AS I ALWAYS DO. I WAS AT 8 M…

BEING A FEW MILES FROM A FRIEND'S HOUSE, I DECIDED IT WOULD BE SAFER TO STOP THERE, SO I CONTINUED ON TO HIS HOUSE. WHEN I PULLED IN THE DRIVEWAY, I NOTICED MY REAR BRAKE ROTOR WAS GLOWING RED AND THE WHOLE CALIPER WAS SMOKING AND HOT. THE BRAKE LINE MELTED AND LEAKED FLUID ON THE HOT CALIPER AND THEN CAUGHT …
