2004 YAMAHA YZF-R1 Engine And Engine Cooling Problems

MOTORCYCLE 2004 YAMAHA R1 THE MOTORCYCLE ENGINE CUTS OUT AND STARTS TO SURGE, AT IDLE THE RPMS DROP BY HALF AND USUALLY DIES TOTALLY. THIS HAPPENS ANYWHERE I STOP AND LET OFF THE GAS. I HAVE ALMOST WRECKED NUMEROUS TIMES BECAUSE OF THIS. IT STARTED ABOUT 1 YEAR AGO AT ABOUT 3000 MILES ON THE ODOMETER. *JB

MOTORCYCLE SURGES HEAVILY GOING DOWN THE ROAD, STALLS AT EVERY STOP SIGN, IT WILL STALL OUT IN TRAFFIC, THE MOTORCYCLE ALSO WILL STALL OUT WHEN GOING AROUND TURNS WHICH IS ALSO VERY DANGEROUS. NOTHING HAS BEEN DONE TO CORRECT THE ISSUE BECAUSE THE DEALER DOESN'T KNOW WHAT'S WRONG WITH IT.*JB

IN THE SUMMER OF 2005, WHILE RIDING MID-TURN, MY 2004 YAMAHA YZF-R1 LURCHED AND CUT-OUT CAUSING ME TO LOW SIDE MY MOTORCYCLE. I RECEIVED MINOR INJURIES AND MY MOTORCYCLE WAS WRECKED AND IS BRANDED SALVAGE ON THE TITLE. AFTER THE INCIDENT AND REPAIRING MY BIKE, APPROXIMATELY TWO WEEKS LATER IT DID THE SAME THING IN TRAFFIC. THE BIKE WILL RUN VERY ROUGH, THE RPM'S WILL DROP, AND THEN THE BIKE WILL CUT-OUT. LOOKING ON THE INTERNET, I HAVE FOUND THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM, BUT ONE OF MANY. THIS PROBLEM STARTS TO OCCUR AROUND THE 5000 MILE MARK ON THE BIKE. THEIR ARE MANY ANSWERS TO THE PROBLEM, BUT NOT TRUE SOLUTIONS. I ONLY WISH THAT THE PROBLEM HAD NOT ARISEN MID-TURN COSTING ME SO DEARLY. THIS IS DEFINITELY A SAFETY ISSUE AS I AM NOT THE ONLY ONE WHO HAS CRASHED AND WHO KNOWS...

THIS FALL MY 2004 YZF R1(YAMAHA MOTORCYCLE) CUT OUR TWICE AT 60 MPH. I WAS LUCKY IN THE FACT THAT I WAS JUST GOING STRAIGHT ON THE HIGHWAY. IF I HAD BEEN GOING ON A TIGHT CURVE THE OUT COME WOULD HAVE BEEN DIFFERENT. WHEN THE ENGINE CUTS OUT IT'S LIKE SLAMMING ON THE REAR BRAKE OR "ENGINE BRAKING", AND ON A CORNER THIS WOULD MAKE YOU WIPE OUT. TALKED TO THE YAMAHA DEALERSHIP IN TOWN BUT THEY HAD NEVER HEARD OF THIS PROBLEM BUT I KNOW OF OTHER PEOPLE THAT HAVE HAD THIS PROBLEM. THIS IS DANGEROUS AND NEEDS TO BE ADDRESSED. I BOUGHT THE BIKE NEW IN MARCH 2004 AND NOW HAS 7900 MILES ON IT. *JB

WHILE DRIVING AT VARIOUS SPEEDS ENGINE STALLED. CONSUMER TOOK VEHICLE TO DEALER FOR INSPECTION SEVERAL TIMES, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED.*AK *BF *NM
