FIBER WASHER FORK DRAIN 3/16 - (Use 97-3893 for Alloy)
Fiber sealing washer for the front fork drain bolt, 3/16, used where a drain plug needs to seat oil-tight.
This is the fiber washer that seals the fork drain bolt at the bottom of the front fork leg, part number 97-0430, also known under the older H430 designation. It's a small sealing washer, 3/16 in the fiber version, and it sits under the drain plug so oil stays where it belongs instead of weeping out around the threads.

The catalog shows this washer turning up across a wide span of front fork listings, along with a few other figures where drain-style fasteners show up, so it's clearly a workhorse part rather than something tied to one specific model year. If you need the alloy version instead of fiber, the catalog points you to 97-3893.
These washers compress and take a set once they've been through a heat cycle or two, so it's not a bad idea to have a couple on hand any time you're draining or refilling the forks. Cheap to keep a spare of, easy to overlook until you've got a drip on the shop floor.
