I have a 2002 Yamaha Breeze YFA1.my ATV smells like oil when it is hot.Not only that it also leaks oil out of the hole on the bottom of the gas of and on switch when it is very hot.The oil will leak everywhere causing it to smoke when the oil touches a hot engine.The gas tank has a hose that goes into the gas off and on switch so I'm hopeing its not gas.
