    Hi all, thinking of getting mushroom tappet adjusters, for my t150v is there anything else I will need, to fit them. Kevin.

    You will need new rocker box gaskets & i’d go for the copper ones and use a little Wellseal when fitting them

    The mushroom heads can indent into the valve stem so I have lash caps to help protect the stems. Replacing the caps being easier and cheaper than valve replacement. I think you need shorter stem valves though.

    You can of course shorten your existing valves which will remove any previous indentation. Just shorten them by the thickness of the lash caps.

      Apparently late t150v and t160 have short valve stems and the lash caps fit them with out shortening them, but the lash caps are about £10 each,

    If you use lash caps you will need short mushrooms, if you don’t you will need long mushrooms.

      Thanks Angus, it all gets a bit confusing the mushrooms I have are the same size as the existing tappet adjusters on the bike, I take it they will fit with out the lash caps, regards kev.
