2004 YAMAHA ROAD STAR Engine And Engine Coolingengine Problems

I HAVE A 2004 YAMAHA ROAD STAR AND THE REAR VALVE IS STICKING AND WILL SUDDENLY DROP POWERAND RUN ON ONE CYLINDER. I HAVE HAD THIS PROBLEM FOR A WHILE AND IS A VERY DANGEROUS PROBLEM THAT YAMAHA KNOWS ABOUT.

I WAS MERGING ONTO INTERSTATE 80 GETTING UP TO SPEED AND IT STARTED TO SPIT/SPUTTER AND LOST POWER. ALMOST, REAR ENDED BY ANOTHER CAR AT 60 MPH. NOTHING HAS BEEN DONE TO THIS POINT TO REMEDY THE PROBLEM.*AK

2004 ROAD STAR VALVES STICK ON REAR CYLINDER CAUSING A LOSS OF POWER. *NM

I HAVE A 2004 YAMAHA ROADSTAR. AT ABOUT 24,000 MILES IT DEVELOPED STICKING VALVES IN THE REAR CYLINDER HEAD. TALKED WITH DEALER ABOUT THE PROBLEM AND THEY HAD NOT HEARD OF IT. THIS IS A WELL DOCUMENTED SITUATION SO I REFUSED TO LET THEM EVEN MESS WITH IT. TOOK IT APART MYSELF. REAMED THE GUIDES AND LAPPED THE VALVES, PUT IN STRONGER SPRINGS AND PUT IT BACK TOGETHER. RUNS GREAT NOW. YAMAHA NEEDS TO BE TOLD TO DO A RECALL ON THE 2004, 2005 ROADSTAR TO SIMPLY REPLACE THE HEADS. THEY KNOW ABOUT THE PROBLEM AND HAVE FIXED IT ON THE 2006 MODEL. *NM

THE VALVES STICK OPEN ON MY 2004 YAMAHA MOTORCYCLE. THEY STUCK OPEN IN THE MIDDLE OF A LEFT TURN IN A THREE-WAY INTERSECTION AND ALMOST RESULTED IN A HEAD-ON COLLISION. MY DEALER IS AWARE OF THIS PROBLEM AND HAS CHOSE TO IGNORE IT. *NM

I OWN A 2004 YAMAHA ROADSTAR, 1700CC MOTORCYCLE. I HAVE HAD A PROBLEM WITH THE REAR EXHAUST VALVES STICKING FOR THE LAST 20,000 MILES. I HAVE BEEN TO DEALER AFTER DEALER AND HAVE HAD NO SUCCESS IN HAVING MY PROBLEM FIXED. I BELIEVE THERE IS A POTENTIAL SAFETY RISK WITH THIS PROBLEM, BECAUSE THE BIKE WILL SUDDENLY LOSE ALL POWER AND QUIT RUNNING. IT IS JUST A MATTER OF TIME BEFORE SOMEONE HAS THIS HAPPEN AND IS SERIOUSLY INJURED OR EVEN KILLED. *JB
