Good To Know

Q: How do I know this O-ring fits my machine? A: It is listed for Yamaha Moto 4 350 models from 1987 through 1995. Check your model year and carburetor setup before ordering.

Q: Why replace this O-ring? A: A worn or flattened O-ring lets air leak past the carburetor joint, which causes lean running and poor idle. Replacing it during carb service helps restore proper mixture.
