    Power valve bulletin

    Is it possible that anyone here would still has the Service bulletin
    for the original power valve . Just tore down my Xr-1800 , to find six
    bronze bushing power valves. Not sure if I was armed with the bulletin if
    Yamaha would replace these after all these years. 1 pin had fallen out, but
    no piston damage was discovered

    I have access to WSM replacements for 50$ each.
    Would these be a suitable replacement for the original design
