    has anyone had to helical or recoil their exhaust port threads.

    It seems to be 1 and 1/2 inch thread diameter and 16 TPI

    what thread would this be, as its not UNF.

    for a 1975 T150v

    and any luck getting anyone to do a decent job on it.

    many Thanks

    Hi Robert, Richard at P&M have oversize exhaust stubs which aren’t just bits of pipe threaded but heavier, they will tap and fit these for you, my advise is to do all three to be on the safe side whilst the head is off. I do my own for engines which I prepare. Cheers, Dick

      Thanks Dick

      Will do, most of my motor is from P and M, the lightened crank, carillon rods, forged pistons, belt drive and clutch, carbies and valves etc and most other parts in the head.

      So may as well send this head back to them to get done.

      Regards Robert
