2011 CAN-AM SPYDER RS Engine And Engine Cooling Problems

MY LAST RIDE, AS IN PREVIOUS RIDES, WAS ACCOMPANIED BY THE ODOR OF RAW FUEL. AMBIENT TEMPERATURE WAS IN THE MID 50'S. TYPICAL CITY TRAFFIC BUT NO LONG PERIODS OF STANDING STILL. ENGINE TEMPERATURE NORMAL. VOLUME OF FUEL IN THE TANK DOES NOT SEEM TO BE A FACTOR. PARKED THE SPYDER AND, AS IN THE PAST, OBSERVED VAPORS EMITTING FROM THE VENT HOSE UNDER THE FRAME WITH AN OCCASIONAL DROP OF FUEL. REMOVED THE FUEL CAP, FOR THE FIRST TIME, AND OBSERVED THE SOUND OF BOILING LIQUID. WITHOUT ANY DETAIL GIVEN I ASKED MY PASSENGER TO DO LIKEWISE WHICH RESULTED IN AN IDENTICAL OBSERVATION. VERY LITTLE HAS BEEN DONE, PARTICULARLY GIVEN THE ENCLOSED NATURE OF THE VEHICLE, TO PREVENT HEAT RADIATED FROM THE EXHAUST, IN VERY CLOSE PROXIMITY TO THE FUEL TANK, FROM HEATING THE TANK SUFFICIENTLY TO CAUSE THE FUEL TO BOIL. THIS, IN MY OPINION, IS A DISASTER...
