Throttle bodies are reliable and generally trouble free, especially compared with carburettors. But, as with all things mechanical, sooner or later maintenance and/or refurbishment will eventually be required.
So, if carrying out a cosmetic and/or mechanical refurbishment, the more parts you can afford to replace with new the better the results will be, visually and from an operating perspective.
Other related parts you may wish to consider:
Add as many components as you wish to the same shopping cart, new caps 8951416900 & clips 8A71413900 for example, and still only pay the same single fixed price shipping cost.
This component may have other applications within the Yamaha model range, so check by part number rather than the description.
