2013 KTM 690 DUKE Fuelpropulsion System Problems

THE FUEL TANK LEAKS FROM THE GAS CAP. ALSO, THIS IS NOT MY FIRST KTM, WHICH HAS HAD A LEAKING GAS CAP. IT'S MY 3RD ONE. THIS ISSUE IS VERY WELL-DOCUMENTED ON THE FORUMS AS WELL AS ON YOUTUBE. GASOLINE POURS RIGHT OUT OF THE GAS CAP ESPECIALLY WHEN IT IS FULL OR WHEN ACCELERATING OR DECELERATING BRISKLY. I AM FAIRLY CERTAIN THIS IS AN ISSUE TO DO WITH THE HIGH ETHANOL CONTENT PRESENT IN ALL U.S. GAS. THE STANDARD FUEL IS E10, WHICH MEANS 90% GASOLINE AND 10% ETHANOL. THERE HAS ALREADY BEEN A CLASS ACTION LAWSUIT AGAINST DUCATI IN THE PAST FOR THIS ISSUE ALTHOUGH IT HAS CROPPED WITH OTHER MANUFACTURERS. THE ISSUE ARISES FROM A REACTION WITH ETHANOL IN PLASTIC TANKS. IT IS NOT AN ISSUE WITH METAL TANKS. MOST MANUFACTURERS HAVE FIXED THE ISSUE OR STOPPED USING THE PLASTIC. HOWEVER, KTM REMAINS A MAJOR PROBLEM AS...

THIS BEING MY 2ND GAS TANK FROM KTM, AFTER EACH TIME I FILL THE GAS TANK WITH FUEL AND CONTINUING UNTIL THE TANK IS LESS THAN HALF FULL, WHILE RIDING THE MOTORCYCLE, FUEL IS FORCED OUT ONTO THE SURFACE OF THE TANK FROM AROUND THE MOUNTING PLATE/SYSTEM WHERE THE GAS CAP ASSEMBLY IS MOUNTED TO THE TOP OF THE TANK, AND THE GAS RUNS DOWN THE TANK AND ON TOP OF THE MOTOR. EVEN WHEN PARKED AND NOT RUNNING, GAS FUMES ARE COMING THROUGH THE MOUNTING SYSTEM. IT APPEARS THAT THE MOUNTING PLATE OF THE TANK IS WARPING BECAUSE OF THE PLASTIC TANK, NOT ALLOWING THE GASKET BETWEEN THE TWO MOUNTING POINTS OF THE TANK AND THE CAP MOUNTING ASSEMBLY TO SEAL PROPERLY. AFTER DOING SOME RESEARCH ONLINE, I'VE FOUND A FORUM WITH AN 8 PAGE THREAD OF COMPLAINTS OF THE SAME PROBLEM OF THIS TYPE OF MOTORCYCLE.
