Norton 'O' Ring
An 'O' ring listed in both carburetor and front fork/steering head catalog sections, part number 99-0502.
This is an 'O' ring, part number 99-0502, and it shows up twice in the catalog — once in a carburetor listing and once in the front forks and steering head section. That split placement tells you it's a general sealing part used in more than one spot rather than something built for a single job.

Because the same number turns up in two different figures, it's worth double-checking which application you actually need before you order — a carburetor-side sealing ring and one used at the steering head or forks aren't necessarily doing the same work even if the catalog lists them under the same part number.
We don't have more detail on this one beyond where it appears in the books. Call the shop and we'll confirm which application you're after before you order.
