    needle valv dimensions

    my carbs have a 2.5 seat
    does anyone know what the dimensions are on the bs type push in o ring valve are?

    mine looks identical to others but sudco does not list it.
    i have read too small an orifice leads to potential for fuel starvation and burned pistons.

    i put mt cheap caliper on the o ring grrove and get an odd 7.62 mm

    Float needle valve? O-ring for the inlet valve at the float? Nessism knows the demensions. See here http://www.cycleorings.com/ for the o-rings.
    Needle jet?

      just the float valves chef
      i just need to know that the overall dimens are the same as say for an 850

      the darned o rings are suspect
      read a scary article on using alternate replacements with too small an orifice and therfore reduced flow.

        I have valves and o-rings.
        All the BS CV carbs use the same inlet valve and o-ring.

          Good thing, because we don't know what bike he's talking about.
