2005 Yamaha Warrior

BIKE WAS CUTTING OFF (LIKE IT WAS RUNNING OUT OF GAS OR LIKE WHEN YOU HIT THE KILL SWITCH) AT ABOUT 3200 RPM ,80 TO 90 MPH,AND THE ONLY THING I COULD KEEP IT RUNNING WAS TO PULL THE CLUTCH AND GIVE IT A LITTLE GAS. THAT HAS HAPEND SINCE DEC.2005 MANY TIMES SPECIAL ON HWY'S AT THE ABOVE SPEEDS. I'M A MEMBER OF THE RSWAARRIOR.COM FORUM AND A LOT OF OUR MEMBERS WITH SAME BIKE AS MINE,YAMAHA ROAD STAR WARRIOR AND MAJORITY 2005 YEAR MODEL HAD THE SAME PROBLEM AND RESOLVED IT BY INSTALLING A NEW SENSOR.AND FINALY I HAD TO ORDER A NEW PART,CRANK POSITION SENSOR, AND REPLACE IT TODAY 8-24-06. WHEN I TOOK THE OLD PART OUT THE BRACKET,THAT HOLDS THE SENSOR SECURE WITH TWO SCREWS ONE ON EACH SIDE OF THE SENSOR, IT WAS BROKEN ON ONE SIDE AND ONLY ONE SCREW WAS HOLDING THE SENSOR,SO THE SENSOR WASN'T MAKING PROPER CONTACT AND WAS CREATING THE STALING,CUTING OFF.ECT. THAT I STATED ABOVE. I WAS LUCKY THE BRACKET DIDN'T BRAKE COMPLETLY AND THE BIKE DIDN'T QUIT ON ME GOING AT THE HWY SPEEDS,THANK GOD...WE HAVE CONTACT YAMAHA AND REPORT IT THIS FALIURE AND UNTIL THIS DAY 8-24-06 NO RESPONSE... PS: MY BIKE HAS ONLY 8156 MILES ON IT AND I BOUGHT IT NEW 0 MILES ON JAN.OF 2005. *JB

1) CODE 11, CRANKSHAFT POSITION SENSOR. MOTORCYCLE LOSES ALL POWER AT ANY SPEED. MOTORCYCLE INOPERATIVE. NO PRIOR INDICATION OR WARNING. 2) THIS HAS HAPPENED TO ME ON 2 DIFFERENT OCCASIONS. ONCE AT HIGHWAY SPEEDS EXCEEDING 70 MPH. THIS WILL EVENTUALLY LEAD TO A FATALITY AND NEEDS TO BE DEEMED AS A "RECALL". 3) YAMAHA DEALERSHIP REPAIRED WITH NEW PART. PERSONAL COST IN EXCESS OF $400.00. *NM

I HAVE A '05 MIDNIGHT JUST HIT 8200 MILES ON IT. YESTERDAY I WAS ON MY WAY HOME CRUISING AT ABOUT 80 MPH /3K ON THE TACH. I EXPERIENCED A COUPLE OF HESITATIONS AND THE TACH WOULD JUMP UP IN RPM. I SLOWED DOWN A BIT AND THE PROBLEM WENT AWAY. THIS MORNING COMING INTO WORK I WAS CRUISING DOWN THE FREEWAY AGAIN AT 80 WHEN IT HAPPENED AGAIN, THIS TIME, I THOUGH IT WAS POPPING, HESITATING THE TACH WAS JUMPING AROUND AND THE CHECK ENGINE LIGHT WAS FLASHING ON AND OFF. I WAS ABLE TO SLOW TO 70 /2500 RPM AND IT WENT AWAY. BUT AS SOON AS I WOULD TAKE IT BACK UP TO 80 IT WOULD HAPPEN AGAIN. *JB

THE VEHICLE BEING DESCRIBED IS A 2005 YAMAHA ROAD STAR WARRIOR (MOTORCYCLE) (1) I WAS RIDING MY MOTORCYCLE ON I-90 W THROUGH SOUTH DAKOTA. ABOUT 20 MILES WEST OF SIOUX FALLS THE BIKE BEGAN TO BACKFIRE AND JERK VIOLENTLY AT 2500 RPM. I EASED UP ON THE THROTTLE AND SLOWED DOWN TO ABOUT 60 MPH (THE SPEED LIMIT WAS 70 MPH). THE BIKE ACTED FINE AS LONG AS I KEPT GOING SLOW, SO I DECIDED TO TRY AND MAKE IT TO THE YAMAHA SHOP IN RAPID CITY. (2) FORTY MILES EAST OF RAPID CITY, THE BIKE ENGINE CUT OFF WITHOUT WARNING, CAUSING LOSS OF POWER IN THE REAR WHEEL, WHICH CAUSED A DRASTIC DECREASE IN SPEED. THIS INERTIA CAUSED ME TO BE JOLTED FORWARD ON THE BIKE. I WAS ABLE TO KEEP IT UNDER CONTROL AND PULL TO THE SIDE OF A FREEWAY. I LATER FOUND OUT THAT THE "CRANK POSITION SENSOR" WIRE LEADS HAD COME LOOSE, AS THEY ARE NOT STURDY ENOUGH FOR THEIR INTENDED PURPOSE. FORTUNATELY, I WAS GOING STRAIGHT WHEN THE ENGINE CUT OFF. IF I HAD BEEN BANKED IN A CURVE, COMPLETE LOSS OF POWER COULD HAVE EASILY CAUSED AN ACCIDENT AND SERIOUS INJURY. (3) THE MOTORCYCLE WAS TOWED TO BLACKHILLS POWERSPORTS IN RAPID CITY (605-342-5500) WHERE THEY DIAGNOSED THE PROBLEM AND EXPLAINED THAT IT WAS A COMMON PROBLEM WITH THIS MOTORCYCLE. THE MECHANIC EXPLAINED TO ME THAT YAMAHA HAD INSTALLED THE SENSOR WITH INFERIOR WIRES THAT OFTEN FAIL UNDER NORMAL RIDING CONDITIONS. WHEN THE WIRES COME UNHOOKED, THE MOTORCYCLE'S COMPUTER CUTS OFF THE ENGINE. THE YAMAHA CERTIFIED MECHANIC RE-SOLDERED THE CONNECTION AND REPAIRED THE PROBLEM. I THEN RODE IT HOME TO GREAT FALLS, MT WHERE IT GAVE OUT AGAIN ALONG THE WAY. I AM NOW PREPARING TO FIX THIS PROBLEM FOR A SECOND TIME IN A FEW DAYS TIME. *NM
