I called Yamaha Customer Relations(800) 962-7926 about my fuel tank vent tube gurgling and leaking fuel onto the front fender after stopping. And my chain starting to eat the frame. They knew nothing and said there were no technical bullitens either and I would need to report this to a local dealer or they will never know. I can't believe they don't know by now. I called two local dealers and they are not aware of either. I have read here that many have gone back to the dealer and come out with overtightened chains etc. I am really frustrated about this. One of the dealers said he would take pictures and send to Yamaha for reference but they are 50 miles away. Or should I do like the rest and make a anti rub block for the frame and let the gas leak.
