Primary Gasket for 1963-1982 650/750 unit Triumph Motorcycles OEM #71-7009 Bar Type_Smooth Main Jet: 125 (T120/T140 twin-carbStandard primary gasket for your unit Triumph bike. My personal favorite is to smear some clean grease to burnish each side of the gasket and fit it without using gasket cement. That way you can pull your primary cover without the hassle of scraping and fitting a new gasket each time. Fits 1963 1982 unit Triumph 650 c. c. and 750 c. c. motorcycles. Replacement for OEM # 71 7009.
