2005 Yamaha Warrior

WHILE RUNNING THE ENGINE AT AN IDLE AFTER AN OIL CHANGE, A STRONG ODOR OF FUEL WAS DETECTED. THE OIL FILL POINT, A REMOTE TANK, IS UNDER THE SEAT. ALSO UNDER THE SEAT THERE IS A SECOND FUEL TANK, OR SECONDARY TANK THAT HOUSES THE ELECTRIC PUMP USED TO PROVIDE PRESSURIZED FUEL FOR THE FUEL INJECTION. THERE ARE MULTIPLE PORTS IN THE TOP OF THE PUMP HOUSING TOP. THE SMALLEST ONE IS FACING STRAIGHT UP, THIS ONE WAS CRACKED AND LEAKING FUEL. A SEARCH OF THE WEB REVEALED OTHER OWNERS OF THIS VEHICLE HAVE SEEN THE SAME ISSUE. ONE OWNER EVEN STATED A NEW PART FROM YAMAHA BOUGHT AS A REPLACEMENT TO ADDRESS THE CONCERN WAS ALSO BROKEN IN THE SAME LOCATION IN AN INTACT BOX. THE PUMP IS USED ON 2002 TO 2009 YAMAHA ROAD STAR WARRIOR MODELS. THIS COULD VERY EASILY BECOME A FIRE HAZARD. *JS

AT ABOUT 4 MONTHS/5,000 MILES (NOV 2005) MY ENGINE STARTED TO STUMBLE AT ABOUT 3400 RPM IN 4TH OR 5TH GEAR... HIGHWAY SPEEDS. IT WAS INFREQUENT AT FIRST. AS THE TEMPERATE OUTSIDE STARTED TO GET HOTTER, IT BEGAN HAPPENING MORE FREQUENTLY AND ALSO WHEN I WAS RIDING ON ROUGH PAVEMENT. WHEN THE TEMPS GOT INTO THE TRIPLE DIGITS IN MY AREA, THIS PROBLEM MADE ME FEEL UNSAFE ABOUT RIDING MY BIKE. I TOOK THE BIKE (9000 MILES/10 MONTHS) TO THE DEALER (YAMAHA OF NORTH HOLLYWOOD, CA) AND THEY REPLACED THE CRANK POSITION SENSOR (5PX-81670-00-00 PICK UP ASSY) ALSO KNOWN AS THE "PICKUP ROTOR". THIS HAS SOLVED THE PROBLEM FOR NOW. I AM CONCERNED BECAUSE OTHERS HAVE HAD THIS PART REPLACED ONLY TO SEE IT FAIL AGAIN A SHORT TIME LATER.
