Frequently Asked Questions

What is included with the Joker Machine magnetic drain plug replacing 90013-312-000?

One 6061 billet-aluminum magnetic drain plug and its O-ring are included. The plug replaces Honda OEM 90013-312-000 on the listed CB, CL and SL models.

What type of engine debris will the drain-plug magnet collect?

Its neodymium rare-earth magnet attracts ferrous steel particles circulating in the engine oil. Aluminum and other nonmagnetic debris will not stick to the magnet, so normal oil inspection remains important.

What are the thread and clearance dimensions for this Honda magnetic oil plug?

The plug has an M33.7 x 1.5mm thread, takes a 19mm socket, measures 45mm across and extends 19mm below the case. Check that the motorcycle has adequate ground and exhaust clearance before installation.
