If you are already contemplating replacing the friction discs, then you might as well fit new plates and springs as well. You will then be confident that you have done the best possible job, and your clutch will be as smooth and reliable as it was when new.
Other clutch related components you may wish to consider replacing rather than reusing the old worn items:
Don't forget to order the gaskets & seals you require and perhaps this pro-workshop gasket sealant: 08C70K0234M.
Add as many items as you wish to the same shopping cart, new thrust bearing 9350516006 screws 9015705065 for example, and still only pay the same single fixed price shipping cost.
This component may have other, sometimes unrelated, applications within the Yamaha model range. So, please always check by the part-number rather than the description.
