Washer – engine plate bolt (·317" X ·625" X ·064")
A flat washer (.317 in. x .625 in. x .064 in.) used under engine plate and other general bolts, PN 70-8088.
This is a plain flat washer, 70-8088, listed in the parts books as an engine plate bolt washer at .317 in. x .625 in. x .064 in. It shows up across a wide range of figures — crankcase, cylinder and crankshaft, frame, forks, fenders, gas tank and seat fittings — which tells you this is a general-purpose hardware washer used wherever a bolt of the matching size needed a spacer or load-spreading disc, not a part tied to one single spot on the bike.

The alternate number E8088 is the same physical washer under its earlier catalog form. Given how often it turns up in the parts books (26 separate listings across 1968-1973 catalog appearances), it's worth keeping a few on hand since bolts in that size range are common throughout the machine.
We don't have a note tying this specific washer to one bike model or engine family — the catalog data just shows it recurring across a lot of different assemblies. If you're matching it to a particular bolt, check the .317 in. bore against what you're working with before you order.
