Tach Drive Plug (Block Off) with O-ring. This plug is generally used when the tachometer cable drive is removed and still needs to be blocked off to prevent oil leakage. This plug has an o-ring groove machined in it for better sealing.

Several bike builders just cut the stock cable off and left the Honda cable drive end installed in the valve cover. This plug is a much cleaner option in both functionality and looks. These plugs are a real nice touch when you are not using the stock tachometer, and need to eliminate the cable, or are using an electronic tach.

Installs in about a minute, no need to remove the valve cover to remove the tach drive gear assy. Fits tachometer cables that are approximately 15mm in diameter with a 10.5mm groove and held in place with a screw.

• Fits: Honda GL500 (1981-82)
• GL500I (1981-82) Interstate
