2006 YAMAHA XV1700 Engine And Engine Coolingengine Problems

THE MOTORCYCLE SUDDENLY AND WITHOUT NOTICE WILL LOSE POWER DUE TO VALVES STICKING AND CAUSING BIKE TO RUN ON ONLY 1 CYLINDER. IT HAPPENS ON A REGULAR BASIS. THERE HAS BEEN NOTHING DONE TO REMEDY THE PROBLEM BECAUSE YAMAHA TRIES TO LAY BLAME ON THE OWNERS OF THE BIKES. FROM WHAT I HAVE READ THIS IS HAPPENING TO HUNDREDS MAYBE EVEN THOUSANDS OF BIKES! *TR

PURCHASED MOTORCYCLE NEW IN SEPTEMBER 2006. IN DECEMBER 2006 I STARTED HAVING DRIVABLE PROBLEMS. AFTER DISCUSSING WITH OTHER OWNERS OF SIMILAR MOTORCYCLES THEY COMPLAINED ABOUT STICKY EXHAUST VALVES. THEY MADE SOME RECOMMENDATIONS, AND IT TEMPORARILY FIXED THE SYMPTOMS WHICH WERE EXTREME LOSS OF POWER AND POOR RUNNING. THE EXHAUST VALVES STUCK OPENLY AT ANY ENGINE SPEED. THIS OCCURRED DURING TURNS, STRAIGHT AND LEVEL RIDING, ACCELERATING, DECELERATING, ENTERING, EXITING FREEWAYS AND WHILE IN TRAFFIC. THE ENGINE SIZE DIFFERENCE BETWEEN THE 2004, NEWER, AND 1999-2003 MODELS WAS ONLY 70CC, BUT THE CARBURETOR JET SETTINGS WERE MUCH BIGGER. THE CARBURETOR JETTED MUCH, AND WAS MUCH RICHER ON THE 2004-2007 MODELS, WHICH LEAD TO EXCESS GAS BEING PULLED INTO THE COMBUSTION CHAMBER, NOT BEING COMPLETELY BURNT AND CARBON DEPOSITS BEING LEFT ON THE VALVE SEAMS OF THE REAR CYLINDER HEAD. THIS CONDITION ONLY HAPPENED ON THE REAR CYLINDER HEAD. MY PEERS AND MYSELF RETURNED...

IN THE MORNING I GO THROUGH A NORMAL STARTING PROCEDURE OF MOTORCYCLE RECOMMENDED BY THE DEALER AND BY YAMAHA. WITHIN 1 MILE THE ENGINE CHOKED/POPPED, AND BUCKED, ALMOST DIED ON ONE OCCASION ON THE ROAD. AFTER ANOTHER HALF MILE TO A MILE THE ENGINE CLEARED UP AND WILL START AND RAN FINE THE REST OF THE DAY. RECENTLY THE PROBLEM GOT MORE FREQUENT AND SOMETIMES HAPPENED, THOUGH MILDER SYMPTOMS DURING THE DAY. I WAS SCARED THAT THIS WILL HAPPEN IN TRAFFIC ,AND POSSIBLY CAUSE A CRASH AND INJURY. FROM MY DISCUSSIONS WITH OTHER YAMAHA ROAD STAR OWNERS I WAS NOT THE ONLY ONE HAVING THIS PROBLEM. *AK I HAVE BEEN TO TWO YAMAHA DEALERS ABOUT THE PROBLEM. THE FIRST DEALER SAID IT IS NORMAL FOR THIS MODEL BIKE AND WAS QUITE RUDE, SO I DIDN'T GO BACK TO THEM. THE SECOND DEALER WANTED ME TO SPEND MY MONEY TO REPAIR...
