Two little things.
If the cap on your little oil tank cracks or fails somehow. A gas cap for a B&G lawnmower fits perfectly and costs far less than one that has Yamaha on it.
If you need a new sealed choke cable but don't want to pay for the OEM. You can get one at Tractor Supply Company for 12 bucks in the Tractor parts. It is generic, but robust. It is sealed in a plastic black tube, so it will not rust like the ones wrapped in spiral wire. It is not quite long enough to reach your dash, so route it out between the two front seats. It works great and is inexpensive.
