Ness Enterprises first announced its partnership with Taiwan ' s Rough Crafts ( founded by former World Championship custom bike builder Winston Yeh ) around 18 months ago , and since that time it would appear that the biggest problem the collaborators have had has been keeping product on the shelf at the Dublin , California Ness HQ warehouse - such has been the demand .

heads , passes through the backing plate and exits inside the mouth of the throttle body through proprietary shooter tubes . This eliminates the need for any external hoses or hardware for a virtually closed loop system . Specially designed breather bolts are hidden under billet covers for a clean look . The bolt-on design allows the oil catch to be serviced when the service filter element is serviced , but by

PanAm Oil Shut-Off Valves
German parts and accessory specialist W & W Cycles ( Wuerzburg ) says that the spring loaded ball check valves ( to prevent engine oil from seeping down to the crankcase ) in Pre-Twin Cam engines " don ' t last forever " and that " if you try to start such an engine after a lengthy period of inactivity ( over winter for example ), the oil in the crank case can get forcefully ejected via the breather . " This creates an ungodly mess . The conventional fix is to install a manually operated valve in the oil feed line from tank to oil pump can prevent this - but that carries the risk of forgetting to open it , resulting in major engine trouble . And we mean major . " Our preferred and recommended fix is this nifty PanAm shut off valve . It too is also installed in the feed line , but there is one major difference - once closed , the ignition is cut out too . There is no inadvertent starting of the engine with this baby . " The tough chrome plated polyamide housing has several mounting holes which offer all sorts of possibilities to secure it to the frame or other convenient hard points . It fits Big Twins up to the introduction of the Twin Cam in 1999 using 3 / 8 " internal diameter hoses . It measures 31 mm wide , by 42 mm high and 45 mm deep and comes with 30 cm long wires .
