Important Notes on this document: If you are living in the U.S. you will most likely not be able to find a drain plug for a “Nissan Bluebird” and will probably get very strange looks from the guy at the parts counter, or possibly end up with some part for a school bus. If you go with the Nissan plug in the US, request part number 11128-01M01 (thanks Beanache!), or you can simply go to almost any retail automotive parts store like Auto Zone and request a 12mm drain plug with a 1.25 thread pattern. Peter also notes that he soon will be offering a special aluminum blanking plug for sale. I’ll keep you posted on this as I get information.

As with any modification of your motorcycle, I strongly urge you to consult with a qualified mechanic before attempting this procedure. The principals of this website can bare no responsibility for any damage created by the use of this document. Proceed at your own risk.
