MY MOTORCYCLE KEPT LOSING FUEL. I NEVER LEAVE IT LOW ON GAS, BUT ON NUMEROUS OCCASIONS WENT TO RIDE IT AND THE TANK WAS EMPTY. SINCE THEN I FOUND A YOUTUBE VIDEO SHOWING HOW TO REPLACE WHAT BMW NEVER SHOULD HAVE INSTALLED, SAYING THIS IS COMMON IN CA BECAUSE BMW DID NOT USE METAL QUICK DISCONNECTS ON THE FUEL LINES; OUR GAS EATS THE PLASTIC. AT LEAST 10 GALLONS OF GAS DISAPPEARED OVER 4 MONTHS LAST SUMMER. THIS IS A MAJOR FIRE HAZARD AND I AM LUCKY TO BE ALIVE, I GUESS. IT ALSO IS NOT CHEAP TO FIX. THE PARTS ARE AROUND $100. BMW SHOULD FIX THIS, OR PAY FOR PARTS SO I CAN DO IT.
FUEL LINE QUICK DISCONNECTS ON BOTH SUPPLY AND RETURN FAILED CAUSING FUEL LEAK ON TO ENGINE AND EXHAUST. EXTREME FIRE POTENTIAL. QUICK DISCONNECT SEALS AND COMPONENTS ARE INSUFFICIENT TO HANDLE EXPOSURE TO RAW FUEL, IT IS A POOR DESIGN AND BMWNA SHOULD RECALL R1150RT'S DUE TO THIS FAILURE AND FIRE RISK. *TR
