YAMAHA YZ 400

Yamaha's early big-bore two-stroke. Air-cooled, raw, and now well into restoration territory. Get the fitment right on engine internals and chassis bearings or you'll waste money and weekends. Check the fins for cracks. Check the frame mounts for fatigue. Decades of vibration leave their mark, so inspect before you order parts.
