2012 YAMAHA XT1200Z Unknown Or Other Problems

MOTORCYCLE WILL FOR NO REASON DIE OR IDLE FAST AROUND 3,500 RPM. THIS IS VERY DANGEROUS WHEN LETTING OFF THE THROTTLE TO TURN AROUND A CORNER AND THE BIKE DOES NOT SLOW DOWN. IT HAS HAPPENED TO ME ABOUT 5 DIFFERENT RIDE DAYS. IT WOULD STALL WHEN LETTING OFF THE GAS OR ACCELERATE. I ALWAYS WAS ABLE TO LET THE BIKE REST START STOP THE MOTOR 5 TO 30 TIMES AND IT WOULD GO BACK TO NORMAL. I ALMOST WENT OF THE ROAD IN THE MOUNTAINS WHEN IT 1ST HAPPENED. LET OFF THE GAS FOR A TIGHT CORNER AND THE BIKE DID NOT SLOW IT SPEED UP. *TT *CN

THIS MOTORCYCLE STALLS INTERMITTENTLY WHEN I ENGAGE THE CLUTCH. IT SOMETIMES IDLES HIGH WHEN MY HANDS ARE OFF THE THROTTLE. BOTH OF THESE CONDITIONS THAT HAVE PUT ME IN DANGER AS THEY OCCUR WHILE DRIVING IN TRAFFIC AND PUT ME IN A POSITION WHERE I HAVE NO CONTROL OVER THE VEHICLE. IF YOU LOOK AT THE YAMAHA FORUMS (YAMAHASUPERTENERE.COM) YOU'LL SEE THAT THIS HAS HAPPENED TO MANY OWNERS. YOU WILL EVEN FIND VIDEOS OF THIS YEAR AND MODEL MOTORCYCLE MAINTAINING FREEWAY SPEED WHEN THE DRIVER HAS NO HAND ON THE THROTTLE. I'M AFRAID TO RIDE MY MOTORCYCLE IN THIS CONDITION AND CERTAINLY CAN'T SELL IT. AT THIS POINT IT'S A USELESS $9000 VEHICLE. PLEASE HELP.
