Manifold Packing Nuts

Factory style open end wrenches for the large manifold plumber nuts.

Engines with a leaking intake manifold are hard to kickstart and will never run properly. That’s why you need one of these leak testers in your workshop, which will once and for all take the guess work out of your installation job. Just bolt them to your manifold (use the stock gasket!), close both intake valves, by slowly turning the engine and with an air hose hooked-up to the G 1/4” fitting apply up to 10 psi of pressure. Spray soapy water around the gasket and manifold clamps and in case of appearing bubbles you can clearly spot any air leaks in your intake system.

A custom part with a long tradition. This smart little device allows for the use of pull type throttle assemblies with Linkert carbs. After installation the throttle disc will be pulled to open and the spring closes it again, when you release the throttle grip. Each kit comes with two springs to meet individual requirements. The weaker spring (Fn≈23 N) should be sufficient for most outside cable applications, the stronger spring (Fn≈58 N) is recommended for internal or very long throttle cables. Works with all M-series Linkert carbs, when equipped with a 1949-1965 type lever, i.e. OEM# 27260-49.

Brass seals for all Harley models from 1930–54. Exact reproductions of the OEM  manifold seals.

These are the seals many of you have heard about, which will once and for all cure the notorious intake leaks of old manifolds. They are machined from PEEK (polyetheretherketone), a thermoplastic with a melting point of 650°F (343°C). Compared to brass seals this material has superior creep resistance and seal properties and can sustain large stresses over a long service life without significant extrusion.
