I TOOK MY 06 SPORTSMAN 500EFI IN TO MY DEALER BE CUASE OF MISSING, DYING AND OIL LEAKING AND THEY TOOK CARE OF IT WITHIN 3 DAYS IT WAS A BROKEN WIRE TO THE AIR TEMP SENSOR FOR THE MISS WHEN HOT /THE ETC NEEDED ADJUSTMENT FOR THE DYING /AND THEY REPLACED THE VALVE COVER GASKET FOR THE OIL LEAK. I AM HAPPY IT WENT WELL BECAUSE I WAS NOT HAPPY ABOUT HAVING TO TAKE MY NEW WHEELER IN FOR REPAIRS!!
