    TC 250 2010
    It's the second time than I change the exhaust valves, they are perfect but have a lot off wear on the tip.
    Never need adjustment and use the original shims and the Pro-X 0.160 shims ,I check it every month but when have tip wear need to change the valve inmediately, because loss the hardened treatment.
    The tappets don't hammer the valve, because are perfectly adjusted.
    What can be the cause?
    Have anyone steel valves?
    It's a TC 250 2010 (Black head)

    Thanks.
