Check out CMSNL (Europe) and Partzilla (US) for manuals.

About the only thing plastic or nylon in there would be the ballancer chain slipper pad
www.partzilla.com/catalog/yamaha/motorcy...c500a/crank-balancer or maybe the dipstick.

1973 Service manual is in the tech library here. Probably use the DT360 one for things not shown/covered.

The balance chain is a disaster waiting to happen IMHO, I owned a SC500 when new and removed the chain, rode it for years. You may get some vibration but to I never noticed anything horrible. It's a torquey engine so you can short shift and keep the revs down. Those pieces may be from the chain guide.
Thanks Mark

Thanks for the info on manual. Just had a look but can't see anything it could be.

A couple of people already mentioned pretty much the only thing it could be is pieces of the balancer chain guides.
