    Hi All,

    2 are listed by suppliers with 20.64mm and 22.22mm bores. There are other different dimensions described such as overall length and pushrod length, as 2 different servos were used in the 1982-1992 model lifetime.

    Does anybody know the original part number for the earliest type m/c or its actual size?

    or does it matter as many people just bolt on the bigger m/c as an upgrade?

    Thanks!!
