Joker Machine Billet Aluminum Oil Fill Cap


Billet aluminum oil filler cap, available in black, silver or chrome.  Perfect for competition use where safety wiring cap is required.


Give your bike’s crankcase a refined race look with one of these cool oil filler plugs! All CNC machined from 6061-T6 aluminum. Super easy handle design eliminates the need for a “tool” (or coin) to inspect or add oil to your engine. Holes in handle enable “safety wiring” access for racing applications, and add lightness to the part.
