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.

THE REAR CYLINDER VALVES ARE STICKING OPEN WHEN MY 2005 YAMAHA ROADSTAR IS WARMING UP. IT HAPPENS VERY UNEXPECTEDLY AND WITHOUT WARNING CAUSING A LOSS OF POWER. THIS LOSS OF POWER HAS LEFT ME SITTING ALONG A VERY BUSY HIGHWAY WITH A NARROW SHOULDER AS WELL AS ALMOST CAUSED ME TO DROP THE BIKE DURING A LEFT HAND TURN IN FRONT OF ONCOMING TRAFFIC. I SPOKE WITH THE LOCAL DEALERSHIP BUT THEY CLAIMED TO NEVER HEARD OF SUCH A PROBLEM WHILE IT IS WIDELY KNOWN AMONG ROADSTAR RIDERS THAT IT IS A COMMON PROBLEM. IT IS JUST A MATTER OF TIME BEFORE SOMEONE IS INJURED BY THIS. *JB

SINCE MY 2005 YAMAHA ROAD STAR HAD 3000-3500 MILES ON IT, IT HAS DEVELOPED A SEVERE LOSS OF COMPRESSION IN IT'S REAR CYLINDER. THIS CAUSES A SAFETY HAZARD BY NOT PRODUCING THE APPROPRIATE ACCELERATION OF SPEED IN CRUCIAL SITUATIONS. AN EXAMPLE WOULD BE WHILE ACCELERATING WHEN MERGING ONTO A HIGHWAY. THE MOTORCYCLE OFTENTIMES CANNOT PRODUCE THE SPEED REQUIRED TO SAFELY ENTER INTO A MOVING TRAFFIC LANE. I FEAR BEING HIT OR KILLED IN A TRAFFIC ACCIDENT BECAUSE OF IT, POSSIBLY NOT BEING ABLE TO ACCELERATE QUICKLY ENOUGH OUT OF ANOTHER MOTORIST'S WAY. THIS PROBLEM IS CAUSED BY 'STICKY' VALVES/EXCESSIVE CARBON BUILD-UP IN THE REAR CYLINDER AND VALVES. NOTE; BECAUSE MY MODEL IS NOT LISTED AMONG THE YAMAHA MOTORCYCLE MODEL'S LISTED IN THE DROP-DOWN MENU IN THIS COMPLAINT, I SELECTED 'WARRIOR' AS IT IS CLOSELY RELATED. THIS HAS CAUSED ME PROBLEM'S WELL IN EXCESS OF 300 TIMES, AS I HAVE NUMBERED IN THE 'FAILURES' BOX BELOW. ALSO, THE DEFECTIVE COMPONENT IS UNKNOWN TO ME. IN THIS COMPLAINT I WAS ASKED TO SELECT A DEFECTIVE COMPONENT AND IN ORDER TO CONTINUE, I CHOOSE AN ARBITRARY ONE, FOR THE SAKE OF COMPLETING AND SUBMITTING THIS COMPLAINT ONLY. ONE WAS REQUIRED TO CONTINUE, OTHERWISE I COULDN'T ACCOMPLISH COMPLETING THE COMPLAINT. *NM
