When the selector forks become worn, renewal is the only practical solution for a reliable gear change mechanism. Renewal of all the interfacing parts at the same time will provide a smoother more accurate trouble-free change operation.
Also check the change linkage fulcrums for wear which can also cause imprecise changes?
Other parts you may wish to consider:
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 bolts 958170601650W2163100 lever 36Y1814000 & torsion Spring9050832142 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.
