Broken YZ Tank
Thump,I saw the title of your post and had to reply. WE had tank problems with both of our 2000 YZ 125's. They cracked along the line where the radiator shrouds attach. The bikes were kept in the garaged and ridden very little, in fact one of the bikes was only a month old!! I contacted the Yamaha dealer where we bought the bikes and Yamaha replaced both tanks for free saying that there were some bad tanks out there due to the plastic curing was too fast on some batches causing some of the tanks manufactured not to be as flexible when swelling from fuel and heat. . :think Three weeks after the tank replacement, one of the new replacement tanks cracked again in the same spot. They replaced that tank too, but told me it would be the last time. :eek: I put the bikes up for sale within that week and sold them. I didn't want to worry about another tank problem. I now own a '01YZF250 and so far no problems. The bike is 7 months old. Hopefully I won't have problems. I don't know if the dealer or Yamaha will help you because of the year of your bike but it might be worth a try. Last week at our local race track, A friend of ours with a '01 YZ 125 had his tank crack during a race in the same spot our YZ 125 tank cracked. You could see the gas pouring out of the side of his bike as he went by.The problem is still out there!! :scream:
