This washer was never fitted to B models and seemingly first appeared on the C1 and D1. I thought it may be a worthwhile addition to my B models, but I haven't got any of these washers and they are NLA from Kawasaki.
I have a few washers in my collection of old fasteners which look like they would work, but I'd like to know the dimensions of the original for comparison. Has anyone got a genuine flywheel washer lying around from which dimensions could be taken?
ID, OD and thickness please

Thanks in advance,
James
