WHENEVER I STOPPED AND SHUT ENGINE OFF THEN TRY TO RESTART ENGINE ,GASOLINE POURED OUT OF THE BREATHER ,CARBUREATOR SPILLING GAS ON THE HOT ENGINE MAKING THAT A FIRE HAZARD. IT DID IT SEVERAL TIMES DURING THE DAY. I THINK THIS NEEDS TO BE LOOK AT IT MAKES A VERY DANGEROUS SITUATION. THANK YOU

FUEL/PROPULSION SYSTEM

FUEL FILTER ASSEMBLY 5PX-24560-00 HAD AN INCORRECT TOLERANCE FIT AND BEGAN LEAKING FUEL ON TO THE ENGINE. LUCKILY THE UNIT STAYED TOGETHER WHILE THE MOTORCYCLE WAS TRAVELING. UPON REPLACING PART IT SIMPLY FELL APART AND CAUSED ALL FUEL IN THE TANK TO DRAIN. FAILURE DURING TRAVEL WOULD LIKELY CAUSE A FIRE AND INJURY OR DEATH TO THE RIDER.

OUTSIDE TEMPERATURE: 95+F, SUNNY, CLEAR NO PASSENGER, JUST DRIVER JUST PULLED INTO THE DRIVEWAY AFTER AN 60 - 90 MINUTE RIDE. SHUTDOWN MOTORCYCLE. RAW GASOLINE, LEAKING FROM THE CARBURETOR, DRIPPING ONTO THE ENGINE AND EXHAUST PIPES. AMOUNT OF GAS EXPELLED ONTO THE ENGINE, I WOULD ESTIMATE 2OZ - 4OZ. FUEL DELIVERY SYSTEM WAS STOCK AT THAT TIME. NO MODIFICATIONS MADE PRIOR TO THE INCIDENT. READ ON INTERNET FORUMS FOR THIS MOTORCYCLE, THIS IS A COMMON ISSUE FOR THIS BRAND OF MOTORCYCLE. DESCRIPTION OF FUEL DELIVERY SYSTEM. FROM TANK - THROUGH FUEL FILTER - TO ELECTRONIC FUEL PUMP - TO CARBURETOR INLET. FUEL LINE IS RUBBER 5/16" FUEL HOSE FROM TANK - TO FILTER - TO PUMP. METAL FUEL LINE FROM FUEL PUMP TO CARBURETOR. METAL FUEL LINE WAS WRAPPED IN 2,000 DEG F HEAT PROTECTIVE TAPE. THIS METAL FUEL LINE RUNS IN BETWEEN THE CYLINDER HEADS OF THE V-TWIN ENGINE FROM THE FUEL PUMP TO THE CARBURETOR. THIS FUEL SYSTEM IS UNDER CONSTANT PRESSURE FROM THE FUEL PUMP TO THE CARBURETOR. ENGINE HEAT EXPANDS THE COOLER FUEL IN THE FUEL LINES AND CARBURETOR, RESULTING IN FUEL EXPANSION AND BOIL. AS A RESULT, RAW FUEL EXPANDS AND SEEKS ITS WAY OUT OF THE CARBURETOR AND ONTO THE ENGINE AND EXHAUST PIPES. THERE IS NO PRESSURE RELIEF EXCEPT FORCING THE FUEL OUT OF CARBURETOR. OWNER CORRECTIONS / MODIFICATIONS TO PREVENT FUTURE INCIDENTS OF RAW GASOLINE POURING ONTO THE HOT ENGINE AND EXHAUST PIPES. 1. RELOCATE FUEL PUMP TO RIGHT SIDE AWAY FROM ENGINE, REMOVE AND DISCARD METAL FUEL LINE. UTILIZE 5/16 RUBBER FUEL HOSE, WIRE SPRING HOSE PROTECTION, DOUBLE INSULATE WITH 2,000K HEAT PROTECTIVE TAPE. THIS NEW LINE RUNS IN BETWEEN THE CYLINDER HEADS TO THE CARBURETOR. 2. ALTERNATE GRAVITY FED FUEL SYSTEM FIX, INCREASE SIZE OF FLOAT BOWL NEEDLE AND SEAT. REPLACE FUEL PETCOCK WITH HIGH FLOW PETCOCK. VENT STOCK GAS CAP. REMOVE FUEL PUMP.

FUEL SYSTEM, GASOLINE

MY 2005 YAMAHA ROADSTAR WAS LEAKING FUEL FROM THE CARBURETOR WHEN RESTARTING AFTER FUELING UP DURING A LONG ROADTRIP. THE HOT FUEL WAS POURING OUT OF THE CARB AND ONTO MY HOT MUFFLERS. AFRAID THE BIKE WOULD CATCH ON FIRE, I HAD TO WAIT FOR IT TO COOL DOWN TO RESTART WHICH IT DID. I TOOK THE BIKE TO HONDA/YAMAHA OF SAVANNAH WHERE THEY CLEANED THE CARB, REPLACED THE FUEL FILTER AND CLEANED OUT THE WHOLE GAS TANK. THE TECH STATED THERE MIGHT HAVE BEEN DEBRIS IN THE FUEL SYSTEM LEAVING THE NEEDLE VALVE IN THE CARB UNSEATED AND ALLOWING FUEL TO PASS THROUGH AND LEAK OUT. THE TECH TOOK IT FOR A 5 MINUTE TEST RIDE AND THERE WAS NO LEAK AFTER RESTARTING. I DROVE ABOUT 200 HIGHWAY MILES AND REFUELED. WHEN I TRIED TO START THE BIKE, FUEL AGAIN POURED OUT OF THE CARB AND ONTO MY HOT EXHAUST. I LET THE BIKE COOL AND HAD A MECHANIC AT THE STATION LOOK AT THE FUEL FILTER AND CARB NO DEBRIS. I HELPED HIM PULL THE TANK AND WE CHECKED FOR DEBRIS. THERE WAS NO TRASH IN THE FUEL. THE PROBLEM CONTINUES ONLY DURING RESTARTING A HOT ENGINE. I'M CONCERNED ABOUT MY SAFETY AND WOULD LIKE YAMAHA TO LOOK INTO THIS AS THIS IS A COMMONLY REPORTED PROBLEM.

MY 2006 YAMAHA SILVERADO 1700 THAT ONLY HAD 4,700 MILES ON IT WHEN I GOT IT 10/2009 PUKES FUEL FROM THE CARB ALL OVER THE HOT MOTOR POST HOT SHUT DOWN WHICH S A FIRE HAZARD I DIAGNOSED IT TO EXTREME HEAT ISSUES WITH CARB & FLOAT BOWL OVERHEATING / METAL FUEL LINE INBETWEEN THE CYLS/ OVERHEATING/ METAL BODY OF ELEC F-PUMP OVER HEATING ALL FROM THE EXCESSIVE HEAT PRODUCED BY THE LRG 1700CC V-TWIN AIR COOLED MOTOR AND YAMAH NOT PROPERLY /FULLY INSULATING THE COMPLETE FUEL SYSTEM WITH A HI TECH HI TEMP INSULATING MATERIAL TO PROTECT THE IT FROM THE EXCESSIVE HEAT AND STOP THE CARB PUKING FUEL WHEN HOT. I INSULATED MY BIKES COMPLETE FUEL SYSTEM WITH A HIGH TECH SPACE AGE 2,000 DEG INSULATING MATERIAL USED IN AUTO RACING APPS. THAT INCLUDED TRIPLE LAYERING IT ON THE METAL FUEL LINE THAT RUNS INBETWEEN THE CYLS ALONG WITH INSULATING THE CARB FLOAT BOWL & CARB MAIN BODY WHERE IT WOULD NOT INTERFERE WITH THROTTLE CABLES ETC . I ALSO INSULATED THE FUEL FILTER & ASSOCIATED FUEL LINES TOO. WITH STOCK FUEL PUMP COVER INSTALLED AND LRG STOCK AIR CLEANER ASSEMBLY YOU CANT SEE MOST OF THE INSULATING MATERIAL ACCEPT FOR WHERE ITS ON THE FUEL LINES ON F-PUMP & FUEL FILTER. DONG THAT FIXED MY BIKE PUKING FUEL 4 OF EVERY 5 TIMES I SHUT IT DOWN HOT EVEN WITH F-PUMP OFF AND IGN SW OFF. I HAVE ALSO SINCE RUN IT IN 95 DEG HH TEMPS WITH NO CARB PUKING FUEL AT ALL. IF YAMAH STEPPED UP TO THE PLATE AND DID THIS 1.5HR /$20 PROCESS I PUT TOGETHER THEY COULD EITHER STOP ALL CARB PUKE ISSUES OR AT LEAST GREATLY REDUCE IT . THE CARB PUKING RAW FUEL, ONTO THE HOT MOTOR IS A REAL SAFETY ISSUE TOO. WHEN IT DID IT ON MY BIKE IT MADE A HISSING SOUND AND WHITE SMOKE WAS COMING FROM THE FUEL HITTING THE HOT MOTOR AND PUSHROD TUBES LOOKING LIKE IT WAS GOING TO IGNITE ANY SECOND WITH 5 GALS OF FUEL JUST WAITING TO GO UP WITH IT SITTING RIGHT ON TOP. NICE DESIGN WORK FROM YAMAHA THAT WONT TAKE RESP FOR CORRECTING IT SINCE THEY KNOW WHAT ISSUES ARE WITH TODAYS PUMP FUELS WITH RESPECT TO HEAT ISSUES.

GAS PUKES OUT OF THE CARBURETOR ONTO HOT EXHAUST PIPES WHEN ENGINE IS RESTARTED AFTER RUNNING ON A WARM DAY. TROUBLE RESTARTING ENGINE. PUKES OUT ENOUGH TO LEAVE A PUDDLE UNDER BIKE. HAPPENS ALL THE TIME. SERVICE PEOPLE JUST SAID THAT IT WAS THE NATURE OF THE BEAST. THIS WILL CAUSE A FIRE ONE DAY. I HEAR THIS COMPLAINT FROM A LOT OF ROADSTAR OWNERS. YAMAHA DOES NOT ACKNOWLEDGE A PROBLEM. DATES OF INCIDENT RANGE IN ALL SUMMER MONTHS SINCE OWNERSHIP. BOUGHT BIKE NEW FROM DEALERSHIP.

CARBURETOR SPILLS GAS ALL OVER HOT EXHAUST ON RESTART AFTER RIDING. HAPPENS WHEN ENGINE IS HOT. HARD TO RESTART. VERY DANGEROUS. LEAVES POOL OF GAS UNDER HOT BIKE. I OWN 2 OF THESE BIKES AND THEY BOTH DO IT. YAMAHA DOES NOT ACKNOWLEDGE THAT A PROBLEM EXIST.

MY 2006 YAMAHA ROADSTAR EXHIBITS FUEL LEAKAGE OUT OF THE CARBURETOR WHEN THE ENGINE IS HOT. THIS USUALLY OCCURS AFTER STOPPING AND THE ENGINE IS WARM AND HEAT SOAKS THE CARB. THIS IS A VERY COMMON PROBLEM WITH THE MODEL. MY CONCERN IS THE POTENTIAL FOR A FIRE WHILE I AM SITTING ON THE MOTORCYCLE. YAMAHA SERVICE REPS HAVE BEEN CONTACTED AND ARE AWARE OF THE PROBLEM BUT YAMAHA DOES NOT HAVE A FIX IN PLACE AT THIS TIME NOR DID THEY SUGGEST THAT THEY WERE WORKING ON ONE. I WOULD HAVE FOR SOMEONE TO BE BURNT OR KILLED AS A RESULT OF THIS ISSUE.

2007 ROADSTAR SILVERADO MOTORCYCLE. EVER SINCE PURCHASED THE MOTORCYCLE PUKES GASOLINE AFTER RIDING OR STOPPING TO GAS UP. IT CONTINUES TO PUKE GAS IN MY GARAGE AFTER RIDING IT ESPECIALLY DURING THE SUMMER TIME. I NOTICED GAS BEING EJECTED AND BOILING WITHIN THE "V" OF THE TWIN CYLINDERS FROM THE CARBUREATOR. ALSO WHEN I STOP FOR GAS THE MOTORCYCLE WILL PUKE GAS AND NOT ALLOW ME TO RESTART THE MOTORCYCLE.

I RECENTLY TOOK A MOTORCYCLE TRIP TO COLORADO, WHILE THERE I HAD SEVERAL INCIDENTS WHERE ON HOT DAYS MY MOTORCYCLE WOULD OVERFLOW GAS ONTO HOT ENGINE AND PIPES. THIS IS A KNOWN PROBLEM WITH THIS BIKE AND I FEEL THAT, DUE TO THE AMOUNT OF FUEL SPILLING ONTO HOT ENGINE AND PIPES, IT'S ONLY A MATTER OF TIME BEFORE A FIRE AND/OR EXPLOSION OCCURS.

FUEL SYSTEM, GASOLINE

AFTER DRIVING VEHICLE AND MOTOR IS HOT, STOPPING FOR APPROX 15 MIN, THEN WHEN TRYING TO RESTART THE CARB SPRAYS GAS OUT ALL OVER THE BASE OF HOT ENGINE AND EXHAUST PIPE. DOES IT EVERY TIME AFTER TRYING TO RESTART THE HOT(NOT OVERLY HOT, JUST HOT WEATHER) ENGINE. GAS IS BOILED AND VAPORIZED IMMEDIATELY. SEEMS TO BE AN OVERALL DESIGN PROBLEM.

FUEL SYSTEM, GASOLINE

FUEL (GASOLINE) IS SPRAYED FROM REAR PORT OF CARBURETOR. AS MUCH AS 2 OZ. MAY BE EMITTED AND SPRAYED ON HOT EXHAUST PIPES AND ENGINE. THE FUEL IS IMMEDIATELY VAPORIZED. THIS ONLY SEEMS TO OCCUR WHEN THE ENGINE IS HOT, THEN SHUT OFF AND ALLOWED TO SIT FOR APPROXIMATELY 15 MINUTES. IT DOES NOT SPRAY LIQUID GAS IF IMMEDIATELY STARTED OR IF ALLOWED TO COOL. MOTORCYCLE MAY CATCH FIRE IF THE OPERATOR TRIES TO START THE ENGINE AND IT HAPPENS TO COUGH OR BACKFIRE THROUGH THE INTAKE AT THE SAME INSTANT. PROBLEM IS FREQUENT.

IN TEMPERATURES OVER 85 DEGREES WHEN STOPPING FOR GAS MY MOTORCYCLE SPEWS GAS OUT OF THE CARB AND ONTO THE GROUND OR HOT EXHAUST PIPES. THIS IS A COMMON PROBLEM ACCORDING TO THE OWNERS GROUP WEBSITE AND YAMAHA SAYS THEY HAVE NEVER HAD THIS PROBLEM AND OR THAT IT HAS TO DO WITH ETHANOL IN THE GAS. THIS SITUATION HAS A SERIOUS POTENTIAL TO CAUSE A FIRE.

FUEL SYSTEM, GASOLINE

I HAVE DISCOVERED THAT WHEN I SHUT THE ENGINE OFF AFTER RIDING ON A HOT DAY OR AFTER EXTENDED IDLING IN HEAVY TRAFFIC, SOMETHING CAUSES A JET OF GAS TO BE SPRAYED FROM THE RIGHT SIDE OF THE ENGINE BEHIND THE AIR CLEANER COVER, IT FLOWS DOWN THE SIDE OF THE HOT ENGINE VERY NEAR AN EXHAUST PIPE. (HOT ENGINE AND FLOWING GAS NOT GOOD). THE DEALER HAS REPLACED THE FLOAT VALVE AND SEAL. HE IS ORDERING ANOTHER ONE BUT DOESN'T REALLY THINK THAT GOING TO CURE THE PROBLEM. I HAVE BEEN IN CONTACT WITH SEVERAL OTHER YAMAHA MOTORCYCLE OWNERS OF THE ROAD STAR MODEL WITH THE 1700CC ENGINE IN A YAMAHA CHAT ROOM WHO ARE EXPERIENCING THE SAME PROBLEM. YAMAHA IS APPARENTLY DOING NOTHING ABOUT THE CARBURETOR MODELS OF THIS ENGINE BUT WENT TO FUEL INJECTION IN 2007. THIS FUEL EVENT HAS HAPPENED ON SEVERAL OCCASIONS, THE DATE LISTED BELOW IS THE MOST RECENT. THIS CONDITION HAS HAPPENED SEVERAL TIMES SINCE I PURCHASED IT NEW, THE MILEAGE I LISTED IS THE LAST INCIDENT.
