Is it common that wear items like bushings are not available for low grade damper rod forks? (41mmKYB) Or other forks for that matter? Bit of a fright today, parts fiche doesn't show lower bushings (on the chrome stanchion tube). These are worn looking and need replacement. Also sealing ring on damper rod cannot be bought separate from damper rod. That kind of limits a "rebuild". Would anybody know a non OEM suspension bits and bobs supplier?
